GtkFileChooserNative with IFileDialog with extra widget
The GtkFileChooserNative
is a GTK widget for file selection dialogs, and IFileDialog
is the corresponding interface in Windows for file selection dialogs. If you want to combine the functionality of GtkFileChooserNative
with an extra widget in the dialog window when using IFileDialog
on Windows, it would require some platform-specific code.
Here's a general approach to achieve this:
Detect the operating system. You can use platform-specific code or libraries to determine whether the application is running on Windows or a different platform.
Use
GtkFileChooserNative
for file selection dialogs on non-Windows platforms. This can be done using the regular GTK file chooser APIs.On Windows, use the COM interface
IFileDialog
to create a custom file selection dialog with an extra widget. The extra widget can be added using theIFileDialogCustomize
interface.Here's an example using C++ and the Windows API:
cpp#include <Windows.h>
#include <ShObjIdl.h>
// Create an instance of IFileDialog
IFileDialog* pFileDialog;
HRESULT hr = CoCreateInstance(CLSID_FileOpenDialog, NULL, CLSCTX_INPROC_SERVER, IID_PPV_ARGS(&pFileDialog));
// Get the IFileDialogCustomize interface
IFileDialogCustomize* pFileDialogCustomize;
hr = pFileDialog->QueryInterface(IID_PPV_ARGS(&pFileDialogCustomize));
// Add your custom widget to the file dialog using the IFileDialogCustomize interface
// ...
// Show the file dialog
hr = pFileDialog->Show(NULL);
// Get the selected file(s)
// ...
You'll need to consult the Windows documentation for further details on how to customize the
IFileDialog
dialog with an extra widget.
It's important to note that this approach requires platform-specific code and may not be portable across different operating systems.
