Re: Font selection panel as part of notebook

The code prints out the names of the widgets in the font selection widget. Using the names you can figure out the internal widget pointers you want to get from the selection widget. This might take a little trial and error to figure out. Maybe try, if it is a treeview,

Re: Font selection panel as part of notebook

A widget has encapsulated functionality that the designer of the widget does not expect you to use or see in your application code. Changing a "private" widget may have negative consequences for how the widget works. If a widget doesn't have the functionality that you need then file a

Eric, Why am I breaking the design? Is it illegal to do? Thank you. On Sep 24, 2017 7:17 PM, wrote: > > Igor, > > It sounds like you are determined to hack at this. I would recommend the > newer GtkFontChooserWidget but OK. The PangoFcFamily* isn't much help. You > need to

Re: Font selection panel as part of notebook

Igor, It sounds like you are determined to hack at this. I would recommend the newer GtkFontChooserWidget but OK. The PangoFcFamily* isn't much help. You need to get your widget pointers and setup up callbacks on your treeviews. Maybe all you need is to connect a "row-activated" to know if

Re: Flickering with Socket and Plug

Hi Rene, It looks like you are trying to paint a surface 100 times every 16ms. Maybe not such a good thing to do. If you are looking to animate a drawing, GTK has a frame clock that is easy to use. The plug and socket are separate programs. You would start your socket and add one or more

Flickering with Socket and Plug

Hey GTK list, I've uploaded a demo app on https://github.com/rehans/GtkSocketPlugDemo It is very simple and just creates a GtkWindow with a GtkSocket child. A GtkPlug with an GtkDrawingArea attached is connected to the socket. The GtkDrawingArea redraws itself every 16ms and simply paints an
