Re: Does gtk2 provide a case 'in'-sensitive text search via 'gtk_text_iter_..._search'?

[Eric Cashon via gtk-app-devel-list]

 

I worked on this a little more and tried to make it UTF-8 compliant. 
Highlighted the text also. It should still be efficient since it is only doing 
a single pass over each char. I am sure there are things that I haven't 
considered but it does a little more than the first try at it.

There are a lot of different functions that you can branch off with this. Most 
are supplied by GTK+ but you never know when you will have need for a special 
purpose function for a text buffer.

Screencasting GNOME Under Wayland

[M . Hanny Sabbagh]

Hello.


I am working on a simple screen recorder for GNOME under Wayland, built with 
GTK+.


Because Wayland doesn't allow capturing the screen due to security reasons. I 
was trying to capture the desktop in the same way as the built-in screencast 
tool. Using the D-Bus API.


This is the last thing I have reached: https://pastebin.mozilla.org/8969728


However, it gives me only one frame. I thought it would run a loop in the 
background or something until StopScreencast is called again. What's the thing 
I am missing here?


Thank you.

Re: Prefered way to change the main window initial size

[elboulangero]

Hey, maybe I'm asking a very silly question, but still, if anyone who
could point me in the right direction, it would really be appreciated.

Thanks !

caret-color (and caret-width?)

[Richard Shann]

I see at

https://developer.gnome.org/gtk3/stable/chap-css-properties.html

that there is a caret-color property. Is it possible to change the
thickness of the text caret?

and, how exactly is caret-color supposed to be set I have:

str = "GtkTextView {caret-color: rgb(255,0,80);}";
gcp= gtk_css_provider_new();
gtk_css_provider_load_from_data(gcp, str, -1, 0);
gtk_style_context_add_provider(gsc, GTK_STYLE_PROVIDER(gcp), 
GTK_STYLE_PROVIDER_PRIORITY_APPLICATION);

but this doesn't seem to work (I have other code such as

str =  "GtkTextView:selected {background-color: rgb(200,128,0);}";
gcp= gtk_css_provider_new();
gtk_css_provider_load_from_data(gcp, str, -1, 0);
gtk_style_context_add_provider(gsc, GTK_STYLE_PROVIDER(gcp), 
GTK_STYLE_PROVIDER_PRIORITY_APPLICATION);

working nicely).
