The difference between TextWindowType::Text and TextWindowType::Widget (original) (raw)

February 4, 2025, 1:52pm 1

Can’t understand from documentation the difference.

I’m using following construction to detect TextTag location for links in TextBuffer

primary_button_controller.connect_released({
    move |_, _, window_x, window_y| {
        let (buffer_x, buffer_y) = text_view.window_to_buffer_coords(
            TextWindowType::Text,
            window_x as i32,
            window_y as i32,
        );

        if let Some(iter) = text_view.iter_at_location(buffer_x, buffer_y) {
            for tag in iter.tags() {
            // ..

Both variants are working, which one is better to choose in this case?
Thanks

Hi,

GtkTextView have the possibility to add left/right/top/bottom “TextWindows” (typically a left one to display line numbers), that will shift and reduce the actual main text area (the GTK_TEXT_WINDOW_TEXT one).

If you don’t use any left or top textwindow, then there will be no shift of the coordinates origins, so window_to_buffer_coords() on GTK_TEXT_WINDOW_TEXT and GTK_TEXT_WINDOW_WIDGET will return the same buffer position.

In general, if you receive the (x,y) coordinates from a Gesture attached to the GtkTextView widget, then you should use GTK_TEXT_WINDOW_WIDGET to be safe.
