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 GtkWindow, widgets with expand=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 container can decide how the expandability of children affects the expansion of the container 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.

Parameters

expand gboolean
 

Whether to expand.
