When the compiler hits IGFD, WIN32 is only set if standard extensions are enabled. (Why?)
IGFD identifies Windows via WIN32 instead of _WIN32. (Why?)
- WIN32 is needed for #ifdef-gated Windows-specific methods in the header & code files.
- There's fallback code in the code file to set WIN32 if _WIN32 or __WIN32__ is set.
- Which is hit *after* the header gets included, so the header doesn't expose required methods.
-> Boom, error!
Workaround by moving the fallback into the header.

ImGuiFileDialog
Purpose
ImGuiFileDialog is a file selection dialog built for (and using only) Dear ImGui.
My primary goal was to have a custom pane with widgets according to file extension. This was not possible using other solutions.
Structure
- The library is in Lib_Only branch
- A demo app can be found the master branch
This library is designed to be dropped into your source code rather than compiled separately.
From your project directory:
mkdir lib <or 3rdparty, or externals, etc.>
cd lib
git clone https://github.com/aiekick/ImGuiFileDialog.git
git checkout Lib_Only
These commands create a lib directory where you can store any third-party dependencies used in your project, downloads
the ImGuiFileDialog git repository and checks out the Lib_Only branch where the actual library code is located.
Add lib/ImGuiFileDialog/ImGuiFileDialog.cpp to your build system and include
lib/ImGuiFileDialog/ImGuiFileDialog.h in your source code. ImGuiFileLib will compile with and be included directly in
your executable file.
If, for example, your project uses cmake, look for a line like add_executable(my_project_name main.cpp)
and change it to add_executable(my_project_name lib/ImGuiFileDialog/ImGuiFileDialog.cpp main.cpp). This tells the
compiler where to find the source code declared in ImGuiFileDialog.h which you included in your own source code.
Requirements:
You must also, of course, have added Dear ImGui to your project for this to work at all.
dirent v1.23 is required to use ImGuiFileDialog under Windows. It is included in the Lib_Only branch for your convenience.
Features
- Separate system for call and display
- Can have many function calls with different parameters for one display function, for example
- Can create a custom pane with any widgets via function binding
- This pane can block the validation of the dialog
- Can also display different things according to current filter and UserDatas
- Advanced file style for file/dir/link coloring / icons / font
- Multi-selection (ctrl/shift + click) :
- 0 => Infinite
- 1 => One file (default)
- n => n files
- Compatible with MacOs, Linux, Windows
- Windows version can list drives
- Supports modal or standard dialog types
- Select files or directories
- Filter groups and custom filter names
- Keyboard navigation (arrows, backspace, enter)
- Exploring by entering characters (case insensitive)
- Directory bookmarks
- Directory manual entry (right click on any path element)
- Optional 'Confirm to Overwrite" dialog if file exists
- Thumbnails Display (agnostic way for compatibility with any backend, sucessfully tested with OpenGl and Vulkan)
- C Api (succesfully tested with CimGui)
Singleton Pattern vs. Multiple Instances
Single Dialog :
If you only need to display one file dialog at a time, use ImGuiFileDialog's singleton pattern to avoid explicitly declaring an object:
ImGuiFileDialog::Instance()->method_of_your_choice();
Multiple Dialogs :
If you need to have multiple file dialogs open at once, declare each dialog explicity:
ImGuiFileDialog instance_a;
instance_a.method_of_your_choice();
ImGuiFileDialog instance_b;
instance_b.method_of_your_choice();
Simple Dialog :
void drawGui()
{
// open Dialog Simple
if (ImGui::Button("Open File Dialog"))
ImGuiFileDialog::Instance()->OpenDialog("ChooseFileDlgKey", "Choose File", ".cpp,.h,.hpp", ".");
// display
if (ImGuiFileDialog::Instance()->Display("ChooseFileDlgKey"))
{
// action if OK
if (ImGuiFileDialog::Instance()->IsOk())
{
std::string filePathName = ImGuiFileDialog::Instance()->GetFilePathName();
std::string filePath = ImGuiFileDialog::Instance()->GetCurrentPath();
// action
}
// close
ImGuiFileDialog::Instance()->Close();
}
}
Directory Chooser :
To have a directory chooser, set the file extension filter to nullptr:
ImGuiFileDialog::Instance()->OpenDialog("ChooseDirDlgKey", "Choose a Directory", nullptr, ".");
In this mode you can select any directory with one click and open a directory with a double-click.
Dialog with Custom Pane :
The signature of the custom pane callback is:
for C++ :
void(const char *vFilter, IGFDUserDatas vUserDatas, bool *vCantContinue)
for C :
void(const char *vFilter, void* vUserDatas, bool *vCantContinue)
Example :
static bool canValidateDialog = false;
inline void InfosPane(cosnt char *vFilter, IGFDUserDatas 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, UserDatas("InfosPane"));
// display and action if ok
if (ImGuiFileDialog::Instance()->Display("ChooseFileDlgKey"))
{
if (ImGuiFileDialog::Instance()->IsOk())
{
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()->Close();
}
}
File Style : Custom icons and colors by extension
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_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
ImGuiFileDialog accepts icon font macros as well as text tags for file types.
ImGuIFontStudio is useful here. I wrote it to make it easy to create custom icon sets for use with Dear ImGui.
It is inspired by IconFontCppHeaders, which can also be used with ImGuiFileDialog.
samples :
// define style by file extention and Add an icon for .png files
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 by file who are containing this string
ImGuiFileDialog::Instance()->SetFileStyle(IGFD_FileStyleByContainedInFullName, ".git", ImVec4(0.9f, 0.2f, 0.0f, 0.9f), ICON_IGFD_BOOKMARK);
all of theses can be miwed with IGFD_FileStyleByTypeDir / IGFD_FileStyleByTypeFile / IGFD_FileStyleByTypeLink
like theses by ex :
ImGuiFileDialog::Instance()->SetFileStyle(IGFD_FileStyleByTypeDir | IGFD_FileStyleByContainedInFullName, ".git", ImVec4(0.9f, 0.2f, 0.0f, 0.9f), ICON_IGFD_BOOKMARK);
ImGuiFileDialog::Instance()->SetFileStyle(IGFD_FileStyleByTypeFile | IGFD_FileStyleByFullName, "cmake", ImVec4(0.5f, 0.8f, 0.5f, 0.9f), ICON_IGFD_SAVE);
this sample code of master/main.cpp produce the picture above :
ImGuiFileDialog::Instance()->SetFileStyle(IGFD_FileStyleByExtention, ".cpp", ImVec4(1.0f, 1.0f, 0.0f, 0.9f));
ImGuiFileDialog::Instance()->SetFileStyle(IGFD_FileStyleByExtention, ".h", ImVec4(0.0f, 1.0f, 0.0f, 0.9f));
ImGuiFileDialog::Instance()->SetFileStyle(IGFD_FileStyleByExtention, ".hpp", ImVec4(0.0f, 0.0f, 1.0f, 0.9f));
ImGuiFileDialog::Instance()->SetFileStyle(IGFD_FileStyleByExtention, ".md", ImVec4(1.0f, 0.0f, 1.0f, 0.9f));
ImGuiFileDialog::Instance()->SetFileStyle(IGFD_FileStyleByExtention, ".png", ImVec4(0.0f, 1.0f, 1.0f, 0.9f), ICON_IGFD_FILE_PIC); // add an icon for the filter type
ImGuiFileDialog::Instance()->SetFileStyle(IGFD_FileStyleByExtention, ".gif", ImVec4(0.0f, 1.0f, 0.5f, 0.9f), "[GIF]"); // add an text for a filter type
ImGuiFileDialog::Instance()->SetFileStyle(IGFD_FileStyleByTypeDir, nullptr, ImVec4(0.5f, 1.0f, 0.9f, 0.9f), ICON_IGFD_FOLDER); // for all dirs
ImGuiFileDialog::Instance()->SetFileStyle(IGFD_FileStyleByTypeFile, "CMakeLists.txt", ImVec4(0.1f, 0.5f, 0.5f, 0.9f), ICON_IGFD_ADD);
ImGuiFileDialog::Instance()->SetFileStyle(IGFD_FileStyleByFullName, "doc", ImVec4(0.9f, 0.2f, 0.0f, 0.9f), ICON_IGFD_FILE_PIC);
ImGuiFileDialog::Instance()->SetFileStyle(IGFD_FileStyleByTypeDir | IGFD_FileStyleByContainedInFullName, ".git", ImVec4(0.9f, 0.2f, 0.0f, 0.9f), ICON_IGFD_BOOKMARK);
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 that corresponds to a group of filters using this syntax:
custom_name1{filter1,filter2,filter3},custom_name2{filter1,filter2},filter1
When you select custom_name1, filters 1 to 3 will be applied. The characters { and } are reserved. Don't use them
for filter names.
this 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, ".");
will produce :
Multi Selection
You can define in OpenDialog/OpenModal call the count file you want to select :
- 0 => infinite
- 1 => one file only (default)
- n => n files only
See the define at the end of these funcs after path.
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 set the minimum and/or maximum size of the dialog:
ImVec2 maxSize = ImVec2((float)display_w, (float)display_h); // The full display area
ImVec2 minSize = maxSize * 0.5f; // Half the display area
ImGuiFileDialog::Instance()->Display("ChooseFileDlgKey", ImGuiWindowFlags_NoCollapse, minSize, maxSize);
Detail View Mode
Dear ImGui just released an improved table API. If your downloaded version of Dear ImGui includes the beta version of
table support (included for some time now) you can enable table support by uncommenting #define USE_IMGUI_TABLES in
you custom config file (CustomImGuiFileDialogConfig.h)
If your version of Dear ImGui has finalized tables support, it will be enabled by default.
Exploring by keys
You can activate this feature by uncommenting #define USE_EXPLORATION_BY_KEYS
in your custom config file (CustomImGuiFileDialogConfig.h)
You can also uncomment the next lines to define navigation 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 jump to a point in the file list by pressing the corresponding key of the first filename character.
As you see the current item is flashed by default for 1 second. You can define the flashing lifetime with the function
ImGuiFileDialog::Instance()->SetFlashingAttenuationInSeconds(1.0f);
Bookmarks
You can create/edit/call path bookmarks and load/save them.
Activate this feature by uncommenting: #define USE_BOOKMARK in your custom config file (CustomImGuiFileDialogConfig.h)
More customization options:
#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 to edit the displayed name corresponding to a path
- Double-click on the label to apply the bookmark
You can also serialize/deserialize bookmarks (for example to load/save from/to a file):
Load => ImGuiFileDialog::Instance()->DeserializeBookmarks(bookmarString);
Save => std::string bookmarkString = ImGuiFileDialog::Instance()->SerializeBookmarks();
(please see example code for details)
Path Edition :
Right clicking on any path element button allows the user to manually edit the path from that portion of the tree.
Pressing the completion key (GLFW uses enter by default) validates the new path. Pressing the cancel key (GLFW
usesescape by default) cancels the manual entry and restores the original path.
Here's the manual entry operation in action:
Confirm Overwrite Dialog :
If you want avoid overwriting files after selection, ImGuiFileDialog can show a dialog to confirm or cancel the operation.
To do so, 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. (by design! :) )
Example code For Standard Dialog :
ImGuiFileDialog::Instance()->OpenDialog("ChooseFileDlgKey",
ICON_IGFD_SAVE " Choose a File", filters,
".", "", 1, nullptr, ImGuiFileDialogFlags_ConfirmOverwrite);
Example code For Modal Dialog :
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, not with GetSelection().
The confirmation dialog will be a non-movable modal (input blocking) dialog displayed in the middle of the current ImGuiFileDialog window.
As usual, you can customize the dialog in your custom config file (CustomImGuiFileDialogConfig.h in this example)
Uncomment these line for customization options:
//#define OverWriteDialogTitleString "The file Already Exist !"
//#define OverWriteDialogMessageString "Would you like to OverWrite it ?"
//#define OverWriteDialogConfirmButtonString "Confirm"
//#define OverWriteDialogCancelButtonString "Cancel"
See the result :
Open / Save dialog Behavior :
ImGuiFileDialog uses the same code internally for Open and Save dialogs. To distinguish between them access the various data return functions depending on what the dialog is doing.
When selecting an existing file (for example, a Load or Open dialog), use
std::map<std::string, std::string> GetSelection(); // Returns selection via a map<FileName, FilePathName>
UserDatas GetUserDatas(); // Get user data provided by the Open dialog
To selecting a new file (for example, a Save As... dialog), use:
std::string GetFilePathName(); // Returns the content of the selection field with current file extension and current path
std::string GetCurrentFileName(); // Returns the content of the selection field with current file extension but no path
std::string GetCurrentPath(); // Returns current path only
std::string GetCurrentFilter(); // The file extension
Thumbnails Display
You can now, display thumbnails of pictures.
The file resize use stb/image so the following files extentions are supported :
- .png (tested sucessfully)
- .bmp (tested sucessfully)
- .tga (tested sucessfully)
- .jpg (tested sucessfully)
- .jpeg (tested sucessfully)
- .gif (tested sucessfully_ but not animation just first frame)
- .psd (not tested)
- .pic (not tested)
- .ppm (not tested)
- .pgm (not tested)
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 :
// 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;
}
});
// Destroy thumbnails texture
ImGuiFileDialog::Instance()->SetDestroyThumbnailCallback([](IGFD_Thumbnail_Info* vThumbnail_Info)
{
if (vThumbnail_Info)
{
GLuint texID = (GLuint)vThumbnail_Info->textureID;
glDeleteTextures(1, &texID);
glFinish();
}
});
// GPU Rendering Zone // To call for Create/ Destroy Textures
ImGuiFileDialog::Instance()->ManageGPUThumbnails();
How to Integrate ImGuiFileDialog in your project
Customize ImGuiFileDialog :
You can customize many aspects of ImGuiFileDialog by overriding ImGuiFileDialogConfig.h.
To enable your customizations, define the preprocessor directive CUSTOM_IMGUIFILEDIALOG_CONFIG with the path of your custom config file. This path must be relative to the directory where you put the ImGuiFileDialog module.
This operation is demonstrated in CustomImGuiFileDialog.h in the example project to:
- Have a custom icon font instead of labels for buttons or message titles
- Customize the button text (the button call signature must be the same, by the way! :)
The custom icon font used in the example code (CustomFont.cpp and CustomFont.h) was made with ImGuiFontStudio, which I wrote. :)
ImGuiFontStudio uses ImGuiFileDialog! Check it out.
