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

This library is designed to be dropped into your source code rather than compiled separately.

From your project directory:

mkdir lib    
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
  • Custom coloring / icons / text per file extension
  • 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
  • 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();

} }

alt text

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.

directoryChooser

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();

} }

Custom icons and colors by extension

You can define a color for a filter type

ImGuiFileDialog::Instance()->SetExtentionInfos(".cpp", ImVec4(1,1,0, 0.9));
ImGuiFileDialog::Instance()->SetExtentionInfos(".h", ImVec4(0,1,0, 0.9));
ImGuiFileDialog::Instance()->SetExtentionInfos(".hpp", ImVec4(0,0,1, 0.9));
ImGuiFileDialog::Instance()->SetExtentionInfos(".md", ImVec4(1,0,1, 0.9));

alt text

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.

// Add an icon for .png files 
ImGuiFileDialog::Instance()->SetExtentionInfos(".png", ImVec4(0, 1, 1, 0.9), ICON_IMFDLG_FILE_TYPE_PIC);

// Add custom text for .gif files (the default value is [File] ImGuiFileDialog::Instance()->SetExtentionInfos(".gif", ImVec4(0, 1, 0.5, 0.9), "[GIF]");

alt text

Filter Collections

You can define a custom filter name that corresponds to a group of filters using this syntax:

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 :

```cpp 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 : alt text

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

for retrieve the selection you must use :

ImGuiFileDialog::Instance()->GetSelection();

alt text

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);

alt text

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. alt text

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:

  • IGFDKEYUP => Up key for explore to the top
  • IGFDKEYDOWN => Down key for explore to the bottom
  • IGFDKEYENTER => Enter key for open directory
  • IGFDKEYBACKSPACE => 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.

alt text

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

bookmarks.gif

You can also serialize/deserialize bookmarks (for example to load/save from/to a file):

cpp
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 uses
escape
by default) cancels the manual entry and restores the original path.

Here's the manual entry operation in action: inputPathEdition.gif

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 :

ConfirmToOverWrite.gif

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<:string std::string> GetSelection(); // Returns selection via a map
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

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 CUSTOMIMGUIFILEDIALOGCONFIG 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.
