Re: Widget's Fixed Size??

Thanks for your prompt response.

Although I have not tested your suggestion, I had a look at the code and fond some parts of it intriguing, specially the part about 'Gtkmm2ext' I have never seen this in the documentation, not that I have read the entire gtkmm-doc, but I had done a fair amount of reading.

I did a quick search on google and found that this code is part of project called 'Ardour', a media thing.

I am using WinXP, and that program has not yet been ported to lesser operating systems like MSW. But that's another point.

I would appreciate if you  elavorate more on the 'Gtkmm2ext' matter.

 

Again thanks for your imput.

any_widget.set_size_request (width_pixels, height_pixels);

width_pixels or height_pixels can be -1 to leave that dimension "unset".

but its generally a bad idea to do this without some knowledge of font
dimensions, hence you really want something more like:

void
Gtkmm2ext::set_size_request_to_display_given_text (Gtk::Widget &w, const
gchar *text,
                           gint hpadding, gint vpadding)

{
    int height = 0;
    int width = 0;

    w.ensure_style ();
    w.create_pango_layout(text)->get_pixel_size (width, height);

    height += vpadding;
    width += hpadding;

    w.set_size_request(width, height);
}
