// display if (ImGuiFileDialog::Instance()->FileDialog("ChooseFileDlgKey")) { // action if OK if (ImGuiFileDialog::Instance()->IsOk == true) { std::string filePathName = ImGuiFileDialog::Instance()->GetFilePathName(); std::string filePath = ImGuiFileDialog::Instance()->GetCurrentPath(); // action } // close ImGuiFileDialog::Instance()->CloseDialog("ChooseFileDlgKey"); } } ----------------------------------------------------------------------------------------------------------------- ## Directory Chooser : ----------------------------------------------------------------------------------------------------------------- For have only a directory chooser, you just need to specify a filter null : Example code : ImGuiFileDialog::Instance()->OpenDialog("ChooseDirDlgKey", "Choose a Directory", 0, "."); In this mode you can select any directory with one click, and open directory with double click ----------------------------------------------------------------------------------------------------------------- ## Dialog with Custom Pane : ----------------------------------------------------------------------------------------------------------------- Example code : static bool canValidateDialog = false; inline void InfosPane(std::string& vFilter, IGFD::UserDatas vUserDatas, bool *vCantContinue) // if vCantContinue is false, the user cant validate the dialog { ImGui::TextColored(ImVec4(0, 1, 1, 1), "Infos Pane"); ImGui::Text("Selected Filter : %s", vFilter.c_str()); if (vUserDatas) ImGui::Text("UserDatas : %s", vUserDatas); ImGui::Checkbox("if not checked you cant validate the dialog", &canValidateDialog); if (vCantContinue) *vCantContinue = canValidateDialog; } void drawGui() { // open Dialog with Pane if (ImGui::Button("Open File Dialog with a custom pane")) ImGuiFileDialog::Instance()->OpenDialog("ChooseFileDlgKey", "Choose File", ".cpp,.h,.hpp", ".", "", std::bind(&InfosPane, std::placeholders::_1, std::placeholders::_2, std::placeholders::_3), 350, 1, IGFD::UserDatas("InfosPane")); // display and action if ok if (ImGuiFileDialog::Instance()->FileDialog("ChooseFileDlgKey")) { if (ImGuiFileDialog::Instance()->IsOk == true) { std::string filePathName = ImGuiFileDialog::Instance()->GetFilePathName(); std::string filePath = ImGuiFileDialog::Instance()->GetCurrentPath(); std::string filter = ImGuiFileDialog::Instance()->GetCurrentFilter(); // here convert from string because a string was passed as a userDatas, but it can be what you want std::string userDatas; if (ImGuiFileDialog::Instance()->GetUserDatas()) userDatas = std::string((const char*)ImGuiFileDialog::Instance()->GetUserDatas()); auto selection = ImGuiFileDialog::Instance()->GetSelection(); // multiselection // action } // close ImGuiFileDialog::Instance()->CloseDialog("ChooseFileDlgKey"); } } ----------------------------------------------------------------------------------------------------------------- ## File Style ----------------------------------------------------------------------------------------------------------------- You can define style for files/dirs/links in many ways : the style can be colors, icons and fonts the general form is : ImGuiFileDialog::Instance()->SetFileStyle(styleType, criteria, color, icon, font); styleType can be thoses : IGFD_FileStyle_None // define none style IGFD_FileStyleByTypeFile // define style for all files IGFD_FileStyleByTypeDir // define style for all dir IGFD_FileStyleByTypeLink // define style for all link IGFD_FileStyleByExtention // define style by extention, for files or links IGFD_FileStyleByFullName // define style for particular file/dir/link full name (filename + extention) IGFD_FileStyleByContainedInFullName // define style for file/dir/link when criteria is contained in full name samples : define style by file extention ImGuiFileDialog::Instance()->SetFileStyle(IGFD_FileStyleByExtention, ".png", ImVec4(0.0f, 1.0f, 1.0f, 0.9f), ICON_IGFD_FILE_PIC, font1); ImGuiFileDialog::Instance()->SetFileStyle(IGFD_FileStyleByExtention, ".gif", ImVec4(0.0f, 1.0f, 0.5f, 0.9f), "[GIF]"); define style for all directories ImGuiFileDialog::Instance()->SetFileStyle(IGFD_FileStyleByTypeDir, "", ImVec4(0.5f, 1.0f, 0.9f, 0.9f), ICON_IGFD_FOLDER); can be for a specific directory ImGuiFileDialog::Instance()->SetFileStyle(IGFD_FileStyleByTypeDir, ".git", ImVec4(0.5f, 1.0f, 0.9f, 0.9f), ICON_IGFD_FOLDER); define style for all files ImGuiFileDialog::Instance()->SetFileStyle(IGFD_FileStyleByTypeFile, "", ImVec4(0.5f, 1.0f, 0.9f, 0.9f), ICON_IGFD_FILE); can be for a specific file ImGuiFileDialog::Instance()->SetFileStyle(IGFD_FileStyleByTypeFile, ".git", ImVec4(0.5f, 1.0f, 0.9f, 0.9f), ICON_IGFD_FILE); define style for all links ImGuiFileDialog::Instance()->SetFileStyle(IGFD_FileStyleByTypeLink, "", ImVec4(0.5f, 1.0f, 0.9f, 0.9f)); can be for a specific link ImGuiFileDialog::Instance()->SetFileStyle(IGFD_FileStyleByTypeLink, "Readme.md", ImVec4(0.5f, 1.0f, 0.9f, 0.9f)); define style for any files/dirs/links by fullname ImGuiFileDialog::Instance()->SetFileStyle(IGFD_FileStyleByFullName, "doc", ImVec4(0.9f, 0.2f, 0.0f, 0.9f), ICON_IGFD_FILE_PIC); define style for any dirs by file who are containing this string ImGuiFileDialog::Instance()->SetFileStyle(IGFD_FileStyleByTypeDir | IGFD_FileStyleByContainedInFullName, ".git", ImVec4(0.9f, 0.2f, 0.0f, 0.9f), ICON_IGFD_BOOKMARK); define style for any files by file who are containing this string ImGuiFileDialog::Instance()->SetFileStyle(IGFD_FileStyleByTypeFile | IGFD_FileStyleByContainedInFullName, ".git", ImVec4(0.5f, 0.8f, 0.5f, 0.9f), ICON_IGFD_SAVE); ----------------------------------------------------------------------------------------------------------------- ## Filter Collections ----------------------------------------------------------------------------------------------------------------- you can define a custom filter name who correspond to a group of filter you must use this syntax : custom_name1{filter1,filter2,filter3},custom_name2{filter1,filter2},filter1 when you will select custom_name1, the gorup of filter 1 to 3 will be applied the reserved char are {}, you cant use them for define filter name. Example code : const char *filters = "Source files (*.cpp *.h *.hpp){.cpp,.h,.hpp},Image files (*.png *.gif *.jpg *.jpeg){.png,.gif,.jpg,.jpeg},.md"; ImGuiFileDialog::Instance()->OpenDialog("ChooseFileDlgKey", ICON_IMFDLG_FOLDER_OPEN " Choose a File", filters, "."); ## Multi Selection You can define in OpenDialog/OpenModal call the count file you wan to select : - 0 => infinite - 1 => one file only (default) - n => n files only See the define at the end of these funcs after path. Example code : ImGuiFileDialog::Instance()->OpenDialog("ChooseFileDlgKey", "Choose File", ".*,.cpp,.h,.hpp", "."); ImGuiFileDialog::Instance()->OpenDialog("ChooseFileDlgKey", "Choose 1 File", ".*,.cpp,.h,.hpp", ".", 1); ImGuiFileDialog::Instance()->OpenDialog("ChooseFileDlgKey", "Choose 5 File", ".*,.cpp,.h,.hpp", ".", 5); ImGuiFileDialog::Instance()->OpenDialog("ChooseFileDlgKey", "Choose many File", ".*,.cpp,.h,.hpp", ".", 0); ImGuiFileDialog::Instance()->OpenDialog("ChooseFileDlgKey", "Choose File", ".png,.jpg", ".", "", std::bind(&InfosPane, std::placeholders::_1, std::placeholders::_2, std::placeholders::_3), 350, 1, "SaveFile"); // 1 file ----------------------------------------------------------------------------------------------------------------- ## File Dialog Constraints ----------------------------------------------------------------------------------------------------------------- you can define min/max size of the dialog when you display It by ex : * MaxSize is the full display size * MinSize in the half display size. Example code : ImVec2 maxSize = ImVec2((float)display_w, (float)display_h); ImVec2 minSize = maxSize * 0.5f; ImGuiFileDialog::Instance()->FileDialog("ChooseFileDlgKey", ImGuiWindowFlags_NoCollapse, minSize, maxSize); ----------------------------------------------------------------------------------------------------------------- ## Detail View Mode ----------------------------------------------------------------------------------------------------------------- You can have tables display like that. - uncomment "#define USE_IMGUI_TABLES" in you custom config file (CustomImGuiFileDialogConfig.h in this example) ----------------------------------------------------------------------------------------------------------------- ## Exploring by keys ----------------------------------------------------------------------------------------------------------------- you can activate this feature by uncomment : "#define USE_EXPLORATION_BY_KEYS" in you custom config file (CustomImGuiFileDialogConfig.h in this example) you can also uncomment the next lines for define your keys : * IGFD_KEY_UP => Up key for explore to the top * IGFD_KEY_DOWN => Down key for explore to the bottom * IGFD_KEY_ENTER => Enter key for open directory * IGFD_KEY_BACKSPACE => BackSpace for comming back to the last directory you can also explore a file list by use the current key char. as you see the current item is flashed (by default for 1 sec) you can define the flashing life time by yourself with the function Example code : ImGuiFileDialog::Instance()->SetFlashingAttenuationInSeconds(1.0f); ----------------------------------------------------------------------------------------------------------------- ## Bookmarks ----------------------------------------------------------------------------------------------------------------- you can create/edit/call path bookmarks and load/save them in file you can activate it by uncomment : "#define USE_BOOKMARK" in you custom config file (CustomImGuiFileDialogConfig.h in this example) you can also uncomment the next lines for customize it : Example code : #define bookmarkPaneWith 150.0f => width of the bookmark pane #define IMGUI_TOGGLE_BUTTON ToggleButton => customize the Toggled button (button stamp must be : (const char* label, bool *toggle) #define bookmarksButtonString "Bookmark" => the text in the toggle button #define bookmarksButtonHelpString "Bookmark" => the helper text when mouse over the button #define addBookmarkButtonString "+" => the button for add a bookmark #define removeBookmarkButtonString "-" => the button for remove the selected bookmark * you can select each bookmark for edit the displayed name corresponding to a path * you must double click on the label for apply the bookmark you can also serialize/deserialize bookmarks by ex for load/save from/to file : (check the app sample by ex) Example code : Load => ImGuiFileDialog::Instance()->DeserializeBookmarks(bookmarString); Save => std::string bookmarkString = ImGuiFileDialog::Instance()->SerializeBookmarks(); ----------------------------------------------------------------------------------------------------------------- ## Path Edition : ----------------------------------------------------------------------------------------------------------------- if you click right on one of any path button, you can input or modify the path pointed by this button. then press the validate key (Enter by default with GLFW) for validate the new path or press the escape key (Escape by default with GLFW) for quit the input path edition see in this gif doc/inputPathEdition.gif : 1) button edition with mouse button right and escape key for quit the edition 2) focus the input and press validation for set path ----------------------------------------------------------------------------------------------------------------- ## Confirm to OverWrite Dialog : ----------------------------------------------------------------------------------------------------------------- If you want avoid OverWrite your files after confirmation, you can show a Dialog for confirm or cancel the OverWrite operation. You just need to define the flag ImGuiFileDialogFlags_ConfirmOverwrite in your call to OpenDialog/OpenModal By default this flag is not set, since there is no pre-defined way to define if a dialog will be for Open or Save behavior. (and its wanted :) ) Example code For Standard Dialog : Example code : ImGuiFileDialog::Instance()->OpenDialog("ChooseFileDlgKey", ICON_IGFD_SAVE " Choose a File", filters, ".", "", 1, nullptr, ImGuiFileDialogFlags_ConfirmOverwrite); Example code For Modal Dialog : Example code : ImGuiFileDialog::Instance()->OpenModal("ChooseFileDlgKey", ICON_IGFD_SAVE " Choose a File", filters, ".", "", 1, nullptr, ImGuiFileDialogFlags_ConfirmOverwrite); This dialog will only verify the file in the file field. So Not to be used with GetSelection() The Confirm dialog will be a forced Modal Dialog, not moveable, displayed in the center of the current FileDialog. As usual you can customize the dialog, in you custom config file (CustomImGuiFileDialogConfig.h in this example) you can uncomment the next lines for customize it : Example code : #define OverWriteDialogTitleString "The file Already Exist !" #define OverWriteDialogMessageString "Would you like to OverWrite it ?" #define OverWriteDialogConfirmButtonString "Confirm" #define OverWriteDialogCancelButtonString "Cancel" ----------------------------------------------------------------------------------------------------------------- ## Flags : ----------------------------------------------------------------------------------------------------------------- flag must be specified in OpenDialog or OpenModal * ImGuiFileDialogFlags_ConfirmOverwrite => show confirm to overwrite dialog * ImGuiFileDialogFlags_DontShowHiddenFiles => dont show hidden file (file starting with a .) ----------------------------------------------------------------------------------------------------------------- ## Open / Save dialog Behavior : ----------------------------------------------------------------------------------------------------------------- There is no way to distinguish the "open dialog" behavior than "save dialog" behavior. So you msut adapt the return according to your need : if you want open file(s) or directory(s), you must use : GetSelection() method. you will obtain a std::map of the selection if you want create a file, you must use : GetFilePathName()/GetCurrentFileName() the return method's and comments : Example code : std::map GetSelection(); // Open File behavior : will return selection via a map std::string GetFilePathName(); // Create File behavior : will always return the content of the field with current filter extention and current path std::string GetCurrentFileName(); // Create File behavior : will always return the content of the field with current filter extention std::string GetCurrentPath(); // will return current path std::string GetCurrentFilter(); // get selected filter UserDatas GetUserDatas(); // get user datas send with Open Dialog ----------------------------------------------------------------------------------------------------------------- ## Thumbnails Display ----------------------------------------------------------------------------------------------------------------- You can now, display thumbnails of pictures. The file resize use stb/image so the following files extentions are supported : (.png, .bmp, .tga, .jpg, .jpeg, .gif, .psd, .pic, .ppm, .pgm) only tested with .png, .bmp, .tga, .jpg, .jpeg and .gif by the way Corresponding to your backend (ex : OpenGl) you need to define two callbacks : * the first is a callback who will be called by ImGuiFileDialog for create the backend texture * the second is a callback who will be called by ImGuiFileDialog for destroy the backend texture After that you need to call the function who is responsible to create / destroy the textures. this function must be called in your GPU Rendering zone for avoid destroying of used texture. if you do that at the same place of your imgui code, some backend can crash your app, by ex with vulkan. ex, for opengl : Example code : // Create thumbnails texture ImGuiFileDialog::Instance()->SetCreateThumbnailCallback([](IGFD_Thumbnail_Info *vThumbnail_Info) -> void { if (vThumbnail_Info && vThumbnail_Info->isReadyToUpload && vThumbnail_Info->textureFileDatas) { GLuint textureId = 0; glGenTextures(1, &textureId); vThumbnail_Info->textureID = (void*)textureId; glBindTexture(GL_TEXTURE_2D, textureId); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, (GLsizei)vThumbnail_Info->textureWidth, (GLsizei)vThumbnail_Info->textureHeight, 0, GL_RGBA, GL_UNSIGNED_BYTE, vThumbnail_Info->textureFileDatas); glFinish(); glBindTexture(GL_TEXTURE_2D, 0); delete[] vThumbnail_Info->textureFileDatas; vThumbnail_Info->textureFileDatas = nullptr; vThumbnail_Info->isReadyToUpload = false; vThumbnail_Info->isReadyToDisplay = true; } }); Example code : // Destroy thumbnails texture ImGuiFileDialog::Instance()->SetDestroyThumbnailCallback([](IGFD_Thumbnail_Info* vThumbnail_Info) { if (vThumbnail_Info) { GLuint texID = (GLuint)vThumbnail_Info->textureID; glDeleteTextures(1, &texID); glFinish(); } }); Example code : // GPU Rendering Zone // To call for Create/ Destroy Textures ImGuiFileDialog::Instance()->ManageGPUThumbnails(); ----------------------------------------------------------------------------------------------------------------- ## C API ----------------------------------------------------------------------------------------------------------------- A C API is available let you include ImGuiFileDialog in your C project. btw, ImGuiFileDialog depend of ImGui and dirent (for windows) Sample code with cimgui : // create ImGuiFileDialog ImGuiFileDialog *cfileDialog = IGFD_Create(); // open dialog if (igButton("Open File", buttonSize)) { IGFD_OpenDialog(cfiledialog, "filedlg", // dialog key (make it possible to have different treatment reagrding the dialog key "Open a File", // dialog title "c files(*.c *.h){.c,.h}", // dialog filter syntax : simple => .h,.c,.pp, etc and collections : text1{filter0,filter1,filter2}, text2{filter0,filter1,filter2}, etc.. ".", // base directory for files scan "", // base filename 0, // a fucntion for display a right pane if you want 0.0f, // base width of the pane 0, // count selection : 0 infinite, 1 one file (default), n (n files) "User data !", // some user datas ImGuiFileDialogFlags_ConfirmOverwrite); // ImGuiFileDialogFlags } ImGuiIO* ioptr = igGetIO(); ImVec2 maxSize; maxSize.x = ioptr->DisplaySize.x * 0.8f; maxSize.y = ioptr->DisplaySize.y * 0.8f; ImVec2 minSize; minSize.x = maxSize.x * 0.25f; minSize.y = maxSize.y * 0.25f; // display dialog if (IGFD_DisplayDialog(cfiledialog, "filedlg", ImGuiWindowFlags_NoCollapse, minSize, maxSize)) { if (IGFD_IsOk(cfiledialog)) // result ok { char* cfilePathName = IGFD_GetFilePathName(cfiledialog); printf("GetFilePathName : %s\n", cfilePathName); char* cfilePath = IGFD_GetCurrentPath(cfiledialog); printf("GetCurrentPath : %s\n", cfilePath); char* cfilter = IGFD_GetCurrentFilter(cfiledialog); printf("GetCurrentFilter : %s\n", cfilter); // here convert from string because a string was passed as a userDatas, but it can be what you want void* cdatas = IGFD_GetUserDatas(cfiledialog); if (cdatas) printf("GetUserDatas : %s\n", (const char*)cdatas); struct IGFD_Selection csel = IGFD_GetSelection(cfiledialog); // multi selection printf("Selection :\n"); for (int i = 0; i < (int)csel.count; i++) { printf("(%i) FileName %s => path %s\n", i, csel.table[i].fileName, csel.table[i].filePathName); } // action // destroy if (cfilePathName) free(cfilePathName); if (cfilePath) free(cfilePath); if (cfilter) free(cfilter); IGFD_Selection_DestroyContent(&csel); } IGFD_CloseDialog(cfiledialog); } // destroy ImGuiFileDialog IGFD_Destroy(cfiledialog); ----------------------------------------------------------------------------------------------------------------- ## How to Integrate ImGuiFileDialog in your project ----------------------------------------------------------------------------------------------------------------- ### ImGuiFileDialog require : * dirent v1.23 (https://github.com/tronkko/dirent/tree/v1.23) lib, only for windows. Successfully tested with version v1.23 only * Dear ImGui (https://github.com/ocornut/imgui/tree/master) (with/without tables widgets) ### Customize ImGuiFileDialog : You just need to write your own config file by override the file : ImGuiFileDialog/ImGuiFileDialogConfig.h like i do here with CustomImGuiFileDialogConfig.h After that, for let ImGuiFileDialog your own custom file, you must define the preprocessor directive CUSTOM_IMGUIFILEDIALOG_CONFIG with the path of you custom config file. This path must be relative to the directory where you put ImGuiFileDialog module. ----------------------------------------------------------------------------------------------------------------- ----------------------------------------------------------------------------------------------------------------- Thats all. You can check by example in this repo with the file CustomImGuiFileDialogConfig.h : - this trick was used for have custom icon font instead of labels for buttons or messages titles - you can also use your custom imgui button, the button call stamp must be same by the way :) The Custom Icon Font (in CustomFont.cpp and CustomFont.h) was made with ImGuiFontStudio (https://github.com/aiekick/ImGuiFontStudio) i wrote for that :) ImGuiFontStudio is using also ImGuiFileDialog. ----------------------------------------------------------------------------------------------------------------- ----------------------------------------------------------------------------------------------------------------- */ #ifndef IMGUIFILEDIALOG_H #define IMGUIFILEDIALOG_H #if defined(__WIN32__) || defined(_WIN32) #ifndef WIN32 #define WIN32 #endif // WIN32 #endif // defined(__WIN32__) || defined(_WIN32) #define IMGUIFILEDIALOG_VERSION "v0.6.4" #ifndef CUSTOM_IMGUIFILEDIALOG_CONFIG #include "ImGuiFileDialogConfig.h" #else // CUSTOM_IMGUIFILEDIALOG_CONFIG #include CUSTOM_IMGUIFILEDIALOG_CONFIG #endif // CUSTOM_IMGUIFILEDIALOG_CONFIG // file style enum for file display (color, icon, font) typedef int IGFD_FileStyleFlags; // -> enum IGFD_FileStyleFlags_ enum IGFD_FileStyleFlags_ // by evaluation / priority order { IGFD_FileStyle_None = 0, // define none style IGFD_FileStyleByTypeFile = (1 << 0), // define style for all files IGFD_FileStyleByTypeDir = (1 << 1), // define style for all dir IGFD_FileStyleByTypeLink = (1 << 2), // define style for all link IGFD_FileStyleByExtention = (1 << 3), // define style by extention, for files or links IGFD_FileStyleByFullName = (1 << 4), // define style for particular file/dir/link full name (filename + extention) IGFD_FileStyleByContainedInFullName = (1 << 5), // define style for file/dir/link when criteria is contained in full name }; typedef int ImGuiFileDialogFlags; // -> enum ImGuiFileDialogFlags_ enum ImGuiFileDialogFlags_ { ImGuiFileDialogFlags_None = 0, ImGuiFileDialogFlags_ConfirmOverwrite = (1 << 0), // show confirm to overwrite dialog ImGuiFileDialogFlags_DontShowHiddenFiles = (1 << 1), // dont show hidden file (file starting with a .)
