Change font HL_GTK_TEX_VIEW

[ivogersberg]

Sorry to bother you, I am a newbie using GTK-FORTRAN. I saw the examples, but I still have problems to change the FONT of a multiline text editor created with de function "hl_gtk_text_view_new". Can I change the font name and the font size? Thanks a lot in advance.

Welcome to gtk-fortran!
The HL library is easing coding but does not offer every possible options. But you can without problem mix HL functions and GTK functions. In the TextView widget offers only a function to set a monospace font:
https://docs.gtk.org/gtk4/property.TextView.monospace.html

I found no example of setting other fonts in our gtk-fortran examples. But this StackOverflow answer suggest that you could use Pango markups in your strings (Pango is the GTK library for managing fonts):
https://docs.gtk.org/Pango/pango_markup.html

The Gnome Discourse may also help you: https://discourse.gnome.org/c/platform/5

Please report here if you succeed.

Hi Vicent, Thanks a lot for your anwer, great job yours. I did something like the CSS in MENUBAR example and works fine. Thanks a lot and have a nice day, Ivo Wolff Gersberg COPPE/Federal University of Rio de Janeiro

Great Ivo! Could you post here the main lines of code you use to modify your font in your TextView?
I could then try to include it in one of the gtk-fortran example.

Dear Vincent, I think the function "hl_gtk_file_chooser" has a print inside showing the filename. Always print the filename at the terminal. Thanks and great job, Ivo Wolff Gersberg COPPE/Federal University of Rio de Janeiro

Thanks for pointing that, I will remove it later in August.

[vmagnin]

Done.

Hi Vincent, ! A multiline text editor in which to display the file. tedit = hl_gtk_text_view_new(buttonsBox, editable=TRUE, & & changed=c_funloc(file_edited), ssize = [ 1600_c_int, 600_c_int ] ) call gtk_widget_set_name (tedit, "tedit"//c_null_char) call hl_gtk_box_pack(baseBox, buttonsBox) provider = gtk_css_provider_new () display = gtk_widget_get_display (window) call gtk_css_provider_load_from_data (provider, & "textview#tedit {background-color: black;font-family: monospace;font-size: 16px;}" & //c_null_char, length) call gtk_style_context_add_provider_for_display (display, provider, 800)

Thanks a lot Ivo.
So the CSS Provider is applied to the GTK window, and the TextView widget is then referenced in the CSS code.
I will later try to add such a code in an example as this is a useful basic feature but not so trivial as we could hope...

Hi Vincent, Thank you for your great job. Have a nice day, Ivo

I have updated the examples/bazaar.f90: the TextView now has an ivory background and a Times font. Thanks @ivogersberg

[vmagnin]

I have also noted that in GTK 4.12, gtk_css_provider_load_from_data will be deprecated (therefore still available in GTK<5):
https://docs.gtk.org/gtk4/method.CssProvider.load_from_data.html

The replacement method will be gtk_css_provider_load_from_string:
https://docs.gtk.org/gtk4/method.CssProvider.load_from_string.html

[ivogersberg]

;) Nice. Big hug, Ivo

Hi Vincent, Thanks for the advice. I will try the new function later. Great job. Hugs, Ivo
