Re: IDE to develop app with GTK3 on windows using MSYS2

Have you tried https://www.kdevelop.org/? I have been using it lately and like it for code editing and compilation both on Linux and Windows. It provides more info about the source code than emacs tags does. I haven't gotten the hang of debugging with KDevelop, so I still debug in

Re: IDE to develop app with GTK3 on windows using MSYS2

Why don't you cross compile from Linux to Windows? I have for years maintained several gtk based applications, including the building of installers for windows through make-nsis, and done everything from Linux. Regards, Dov On Mon, May 7, 2018 at 10:30 AM, arkkimede wrote:

Re: GtkRevealer glitches the text view drawing

True that it worths trying queueing a resize. That's why I tried this before and unfortunatelly didn't fix it. In fact, I queued draw too. What I will try now is hide the widget and then show it - П.П. Искаш да разшириш бизнеса си и онлайн? Лесно е! Направи си

Re: Need help in GTK3 Draw event

Hi Dhrubajyoti, The textview widget has text tags built in that you can use to draw rectangles around text. If you want to draw a rectangle to block out text you can match the background and foreground colors. This code works on Ubuntu16.04, GTK3.18 and Python2.7. Give it a try and see

Re: Using Gtk.Builder to create a menubar.

Yes, actions get a prefix depending on where you put them. Every "action container" has a prefix. In your case you add_action() to GtkApplicationWindow and its prefix is "win" I used your code to create an answer to my StackOverflow question > https://stackoverflow.com/a/50051155/4865723 >
