Where wxWidgets shines as a multi-platform UI library is its consistent native look and feel across different operating systems.

Dialogs are no exception. The library offers methods and classes to display system-specific dialogs for everyday tasks, like opening a file, choosing a font, etc.

If you encounter an error message saying “Could not load a pixbuf from icon theme” on Linux, note that it might be just a VSCode error.

As explained in my Menus video (the “Problems with Icons on Linux” chapter), this error may occur when using the default system icons, for example when using submenus and option items in the main menu.

Handling common clipboard tasks for your text fields is a must-have for any serious application that needs to accept keyboard input from the users. Surprisingly, it’s not that easy in wxWidgets, especially considering the differences between platforms (Linux, Mac, and Windows).

I explain the problem in detail in my Text Fields video (the “Clipboard Operations” chapter). In the Menus tutorial, I talk about menus in general and constructing the Edit menu with the clipboard commands in particular.
