File Dialog for Dear ImGui

Simple file dialog for Dear ImGui. Based on L2DFileDialog.

Usage

Add imgui_filedialog.h to your C++ project and include it where you use ImGui.

// Declare outside draw loop
bool m_fileDialogOpen;
ImFileDialogInfo m_fileDialogInfo;

// Optional file filter
m_fileDialogInfo.fileFilterFunc = [](std::string filename) {
  std::size_t found = filename.find(".json");
  return found != std::string::npos;
};

// App logic
if (ImGui::Button("Save File"))
{
    m_fileDialogOpen = true;
    m_fileDialogInfo.type = ImGuiFileDialogType_SaveFile;
    m_fileDialogInfo.title = "Save File";
    m_fileDialogInfo.fileName = "test.json";
    m_fileDialogInfo.directoryPath = std::filesystem::current_path();
}

// Any place in draw loop
if (ImGui::FileDialog(&m_fileDialogOpen, &m_fileDialogInfo))
{
    // Result path in: m_fileDialogInfo.resultPath
}
