ImGui FileBrowser

A simple file-browser for dear-imgui.

Usage

1. Add imgui_filebrowser.cpp to your source files.
2. Include imgui_filebrowser.h.

There are two functions:

bool ImGui::OpenFileBrowser(const std::string& InPath, FileBrowserOption InOption = FileBrowserOption::FILE, const std::set<std::string>& InExt = {});
bool ImGui::FetchFileBrowserResult(const std::string& InPath, std::string& OutSelectedPath);

There are some QOL tricks in the browser:

• Write ".." in the navigation-bar to go up one directory
• Press tab when editing the navigation-bar to auto-complete
• You can specify a base directory by changing the path in GetRelative() and GetLocal(). It is currently set to ..\\content\\.

Example

if (ImGui::Button("Pick file"))
	ImGui::OpenFileBrowser(defaultPath);

std::string result;
if (ImGui::FetchFileBrowserResult(defaultPath, result))
{
	// Do something with the result
}

Notes

• Using the standard library, specifically std::string, std::set and std::filesystem.
• The window size can be changed by changing Width and Height in the FileBrowser class.

TODO:

• Multi-file select
• Search / filters
• Currently relying on that defaultPath is different for each FetchFileBrowserResult() call
