GTK uses reference counting for memory management, meaning objects are automatically freed when they are no longer needed. Developers must manage object references carefully to avoid memory leaks and ensure efficient use of resources. Can GTK applications interact with databases?
This environment variable the default value libdir/gtk-3.0/3.0.0/immodules.cache (libdir has the same meaning here as explained for GTK_PATH). The immodules.cache file is generated by the gtk-query-immodules-3.0 utility. Note that this environment variable is read by GTK+ 2.x too, ...
These are predefined constant images or text with an agreed meaning when used as part of an interface. The rightmost button in Figure 4-7, for example, shows the text “OK” used in conjunction with the curving arrow image. Stock items not only save time for the developer, but they ...
Usually, they will eventually override all the values except the value itself in whatever adjustments you give them, but the results are, in general, undefined (meaning, you’ll have to read the source code to find out, and it may be different from widget to widget). Now, you’re ...
* The data structure below defines a node in the B-tree. */ struct _GtkTextBTreeNode { GtkTextBTreeNode *parent; /* Pointer to parent node, or NULL if * this is the root. */ GtkTextBTreeNode *next; /* Next in list of siblings with the * same parent node, or NULL for end...
The value is the amount “completed”, meaning the amount the progress bar has been filled from 0-100%. It can be a number form 0 to 1, e.g. 0.55 would be 55%. Gtk# has functionality that enables it to display its value in different ways, and to inform the user of its current...
Since GTK 3.15, overlay scrollbars are enabled by default, meaning that scrollbars will be shown only on mouseover in GTK 3 applications. This behavior can be reverted by setting the following environment variable: GTK_OVERLAY_SCROLLING=0. See Environment variables#Graphical environment. ...

After (the text is sharp): This looks good. The only issue is that theIgnorePixelScalingis false by default in all other platforms and the meaning is flipped. Itiswrong and what you have is technically correct, but when I originally implemented the code, the property was to tell the drawi...
