# imgui-filebrowser
|
||||
|
||||
[imgui-filebrowser](https://github.com/AirGuanZ/imgui-filebrowser) is a header-only file browser implementation for [dear-imgui](https://github.com/ocornut/imgui). C++ 17 is required.
|
||||
|
||||
|
||||
|
||||
## Getting Started
|
||||
|
||||
`imfilebrowser.h` should be included after `imgui.h`:
|
||||
|
||||
```cpp
|
||||
#include <imgui.h>
|
||||
#include <imfilebrowser.h>
|
||||
```
|
||||
|
||||
Instead of creating a file dialog with an immediate function call, you need to create a `ImGui::FileBrowser` instance, open it with member function `Open()`, and call `Display()` in each frame. Here is a simple example:
|
||||
|
||||
```cpp
|
||||
#include <imgui.h>
|
||||
#include <imfilebrowser.h>
|
||||
|
||||
int main()
|
||||
{
|
||||
//...initialize rendering window and imgui
|
||||
|
||||
// create a file browser instance
|
||||
ImGui::FileBrowser fileDialog;
|
||||
|
||||
// (optional) set browser properties
|
||||
fileDialog.SetTitle("title");
|
||||
fileDialog.SetTypeFilters({ ".h", ".cpp" });
|
||||
|
||||
// mainloop
|
||||
while(continueRendering)
|
||||
{
|
||||
//...do other stuff like ImGui::NewFrame();
|
||||
|
||||
if(ImGui::Begin("dummy window"))
|
||||
{
|
||||
// open file dialog when user clicks this button
|
||||
if(ImGui::Button("open file dialog"))
|
||||
fileDialog.Open();
|
||||
}
|
||||
ImGui::End();
|
||||
|
||||
fileDialog.Display();
|
||||
|
||||
if(fileDialog.HasSelected())
|
||||
{
|
||||
std::cout << "Selected filename" << fileDialog.GetSelected().string() << std::endl;
|
||||
fileDialog.ClearSelected();
|
||||
}
|
||||
|
||||
//...do other stuff like ImGui::Render();
|
||||
}
|
||||
|
||||
//...shutdown
|
||||
}
|
||||
```
|
||||
|
||||
## Options
|
||||
|
||||
Various options can be combined with '|' and passed to the constructor:
|
||||
|
||||
```cpp
|
||||
enum ImGuiFileBrowserFlags_
|
||||
{
|
||||
ImGuiFileBrowserFlags_SelectDirectory = 1 << 0, // select directory instead of regular file
|
||||
ImGuiFileBrowserFlags_EnterNewFilename = 1 << 1, // allow user to enter new filename when selecting regular file
|
||||
ImGuiFileBrowserFlags_NoModal = 1 << 2, // file browsing window is modal by default. specify this to use a popup window
|
||||
ImGuiFileBrowserFlags_NoTitleBar = 1 << 3, // hide window title bar
|
||||
ImGuiFileBrowserFlags_NoStatusBar = 1 << 4, // hide status bar at the bottom of browsing window
|
||||
ImGuiFileBrowserFlags_CloseOnEsc = 1 << 5, // close file browser when pressing 'ESC'
|
||||
ImGuiFileBrowserFlags_CreateNewDir = 1 << 6, // allow user to create new directory
|
||||
ImGuiFileBrowserFlags_MultipleSelection = 1 << 7, // allow user to select multiple files. this will hide ImGuiFileBrowserFlags_EnterNewFilename
|
||||
};
|
||||
```
|
||||
|
||||
When `ImGuiFileBrowserFlags_MultipleSelection` is enabled, use `fileBrowser.GetMultiSelected()` to get all selected filenames (instead of `fileBrowser.GetSelected()`, which returns only one of them).
|
||||
|
||||
Here are some common examples:
|
||||
|
||||
```cpp
|
||||
// select single regular file for opening
|
||||
0
|
||||
// select multiple regular files for opening
|
||||
ImGuiFileBrowserFlags_MultipleSelection
|
||||
// select single directory for opening
|
||||
ImGuiFileBrowserFlags_SelectDirectory
|
||||
// select multiple directories for opening
|
||||
ImGuiFileBrowserFlags_SelectDirectory | ImGuiFileBrowserFlags_MultipleSelection
|
||||
// select single regular file for saving
|
||||
ImGuiFileBrowserFlags_EnterNewFilename | ImGuiFileBrowserFlags_CreateNewDir
|
||||
// select single directory for saving
|
||||
ImGuiFileBrowserFlags_SelectDirectory | ImGuiFileBrowserFlags_CreateNewDir
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
* double click to enter a directory
|
||||
* single click to (de)select a regular file (or directory, when `ImGuiFileBrowserFlags_SelectDirectory` is enabled)
|
||||
* When `ImGuiFileBrowserFlags_SelectDirectory` is enabled and no directory is selected, click `ok` to choose the current directory as selected result
|
||||
* When `ImGuiFileBrowserFlags_MultipleSelection` is enabled, hold `Shift` or `Ctrl` to select more than one file
|
||||
* When `ImGuiFileBrowserFlags_CreateNewDir` is enabled, click the top-right little button "+" to create a new directory
|
||||
* When `ImGuiFileBrowserFlags_SelectDirectory` is not specified, double click to choose a regular file as selected result.
|
||||
|
||||
## Type Filters
|
||||
|
||||
* (optionally) use `browser.SetTypeFilters({".h", ".cpp"})` to set file extension filters.
|
||||
* ".*" matches with any extension
|
||||
* filters are case-insensitive on Windows platform
|
||||
|
||||
## Note
|
||||
|
||||
The filebrowser implementation queries drive list via Win32 API (only on Windows). Thus `<Windows.h>` is included in `<imfilebrowser.h>`, which may pollute the global namespace. This can be solved by simply moving the `GetDrivesBitMask()` definition into a cpp file.
