Enumeration

GtkAlign

Declaration

enum Gtk.Align

Description [src]

Controls how a widget deals with extra space in a single (x or y) dimension.

Alignment only matters if the widget receives a “too large” allocation, for example if you packed the widget with the GtkWidget:expand flag inside a GtkBox, then the widget might get extra space. If you have for example a 16x16 icon inside a 32x32 space, the icon could be scaled and stretched, it could be centered, or it could be positioned to one side of the space.

Note that in horizontal context GTK_ALIGN_START and GTK_ALIGN_END are interpreted relative to text direction.

GTK_ALIGN_BASELINE support for it is optional for containers and widgets, and it is only supported for vertical alignment. When its not supported by a child or a container it is treated as GTK_ALIGN_FILL.
