GtkPaned is the base class for widgets with two panes, arranged either horizontally (GtkHPaned) or vertically (GtkVPaned). Child widgets are added to the panes of the widget with gtk_paned_pack1() and gtk_paned_pack2(). The division beween the two children is set by default from the size requests of the children, but it can be adjusted by the user.
A paned widget draws a separator between the two child widgets and a small handle that the user can drag to adjust the division. It does not draw any relief around the children or around the separator. (The space in which the separator is called the gutter). Often, it is useful to put each child inside a GtkFrame with the shadow type set to GTK_SHADOW_IN so that the gutter appears as a ridge.
Each child has two options that can be set, resize and shrink. If resize is true, then when the GtkPaned is resized, that child will expand or shrink along with the paned widget. If shrink is true, then when that child can be made smaller than it's requisition by the user. Setting shrink to FALSE allows the application to set a minimum size. If resize is false for both children, then this is treated as if resize is true for both children.
The application can set the position of the slider as if it were set by the user, by calling gtk_paned_set_position().
Example 1. Creating a paned widget with minimum sizes
GtkWidget *hpaned = gtk_hpaned_new(); GtkWidget *frame1 = gtk_frame_new(NULL); GtkWidget *frame2 = gtk_frame_new(NULL); gtk_frame_set_shadow_type (GTK_FRAME (frame1), GTK_SHADOW_IN); gtk_frame_set_shadow_type (GTK_FRAME (frame2), GTK_SHADOW_IN); gtk_widget_set_usize (hpaned, 200 + GTK_PANED (hpaned)->gutter_size, -1); gtk_paned_pack1 (GTK_PANED (hpaned), frame1, TRUE, FALSE); gtk_widget_set_usize (frame1, 50, -1); gtk_paned_pack2 (GTK_PANED (hpaned), frame1, FALSE, FALSE); gtk_widget_set_usize (frame1, 50, -1);
Add a child to the top or left pane with default parameters. This is equivalent to
gtk_paned_pack1(paned, FALSE, TRUE);
Add a child to the bottom or right pane with default parameters. This is equivalent to
gtk_paned_pack1(paned, FALSE, FALSE);
#define gtk_paned_handle_size gtk_paned_set_handle_size
Old name for gtk_paned_set_handle_size()
#define gtk_paned_gutter_size gtk_paned_set_gutter_size
Old name for gtk_paned_set_gutter_size()
Add a child to the top or left pane.
Add a child to the bottom or right pane.
Set the width of the gutter. (The area between the two panes).
Set the the handle size to size x size pixels.
Set the position of the separator, as if set by the user. If position is negative, the remembered position is forgotten, and the division is recomputed from the the requisitions of the children.
