Method
GtkWidgetset_hexpand
Declaration [src]
void
gtk_widget_set_hexpand (
GtkWidget* widget,
gboolean expand
)
Description [src]
Sets whether the widget would like any available extra horizontal space.
When a user resizes a window, widgets with expand set to true generally receive the extra space. For example, a list or scrollable area or document in your window would often be set to expand.
Call this function to set the expand flag if you would like your widget to become larger horizontally when the window has extra room.
By default, widgets automatically expand if any of their children
want to expand. (To see if a widget will automatically expand given
its current children and state, call gtk_widget_compute_expand().
A widget can decide how the expandability of children affects its
own expansion by overriding the compute_expand virtual method on
GtkWidget.).
Setting hexpand explicitly with this function will override the automatic expand behavior.
This function forces the widget to expand or not to expand,
regardless of children. The override occurs because
gtk_widget_set_hexpand() sets the hexpand-set property (see
gtk_widget_set_hexpand_set()) which causes the widget’s hexpand
value to be used, rather than looking at children and widget state.
