ImGui_Explorer

A simple file explorer / file picker / folder picker using ImGui & std::filesystem Works with ImGuiSFML to handle icons, which provides a nice SFML, see here https://github.com/Bousk/ImGuiSFML If you're not using it already and don't intend to, you'll need to provide a replacement for GLHandleToImTexture method and change the sf::Texture (SFML texture) to yours

How to use

// Create an instance of the explorer
FilePicker mImguiFilePicker;

// You can then assign icons to file extensions for better readibility when in use
sf::Texture iniTex;
iniTex.loadFromFile("Icons/Ini.png");
mImguiFilePicker.SetFileIcon(".ini", iniTex);
// You can also assign icon to folders
sf::Texture folderTex;
folderTex.loadFromFile("Icons/Folder.png");
mImguiFilePicker.SetFolderIcon(folderTex);
// You can assign default icon to files whose extensions don't have specific icon
sf::Texture defaultFileTex;
defaultFileTex.loadFromFile("Icons/File.png");
mImguiFilePicker.SetDefaultFileIcon(defaultFileTex);

// Then call regularly, to update the explorer/picker
mImguiFilePicker.Update();
    
// To start using the picking capability    
// To pick a file with no extension filter
if (ImGui::Button("Open file picker"))
    mImguiFilePicker.PickFile(std::filesystem::current_path(), [&](const std::filesystem::path& selectedPath) {});
// To pick a file with specific filter
if (ImGui::Button("Open file picker"))
    mImguiFilePicker.PickFile(std::filesystem::current_path(), [&](const std::filesystem::path& selectedPath) {}, std::vector<std::string>(1, ".ini"));
// To pick a folder
if (ImGui::Button("Open folder picker"))
    mImguiFilePicker.PickFolder(std::filesystem::current_path(), [&](const std::filesystem::path& selectedPath) {});
