I'm working on GtkSpinButton (GTK2/GTK3) to make another control. (DateTime).
As part of the task, I need to add a button 'next to' the GtkSpinButton to influence the content in GtkSpinButton. (when you click it, a calendar pops out). However, when I add a button next to the control, it is not visible or parts of it are cut off.
To solve this in GTK3, I added margin on the right:
gtk_widget_set_margin_end(.., buttonSize) @since 3.12
gtk_widget_set_margin_right(.., buttonSize) @since 3.0
This works nicely. However, I'm struggling to find something equivalent in gtk2.
Is there a margin in gtk2?
