Interfaces

GtkAlignment implements AtkImplementorIface and GtkBuildable.

Detailed Description

The GtkAlignment widget controls the alignment and size of its child widget. It has four settings: xscale, yscale, xalign, and yalign.

The scale settings are used to specify how much the child widget should expand to fill the space allocated to the GtkAlignment. The values can range from 0 (meaning the child doesn't expand at all) to 1 (meaning the child expands to fill all of the available space).

The align settings are used to place the child widget within the available area. The values range from 0 (top or left) to 1 (bottom or right). Of course, if the scale settings are both set to 1, the alignment settings have no effect.

Structures

GtkAlignment

The GtkAlignment struct contains private data only, and should be accessed using the functions below.

Convenient Construction

gtkAlignment is the equivalent of gtkAlignmentNew.

Properties

bottom-padding [numeric : Read / Write]

The padding to insert at the bottom of the widget. Allowed values: <= G_MAXINT Default value: 0 Since 2.4

left-padding [numeric : Read / Write]

The padding to insert at the left of the widget. Allowed values: <= G_MAXINT Default value: 0 Since 2.4

right-padding [numeric : Read / Write]

The padding to insert at the right of the widget. Allowed values: <= G_MAXINT Default value: 0 Since 2.4

top-padding [numeric : Read / Write]

The padding to insert at the top of the widget. Allowed values: <= G_MAXINT Default value: 0 Since 2.4

xalign [numeric : Read / Write]

Horizontal position of child in available space. 0.0 is left aligned, 1.0 is right aligned. Allowed values: [0,1] Default value: 0.5

xscale [numeric : Read / Write]

If available horizontal space is bigger than needed for the child, how much of it to use for the child. 0.0 means none, 1.0 means all. Allowed values: [0,1] Default value: 1

yalign [numeric : Read / Write]

Vertical position of child in available space. 0.0 is top aligned, 1.0 is bottom aligned. Allowed values: [0,1] Default value: 0.5

yscale [numeric : Read / Write]

If available vertical space is bigger than needed for the child, how much of it to use for the child. 0.0 means none, 1.0 means all. Allowed values: [0,1] Default value: 1
