The gtk_widget_set_uposition()
function is used to set the position of any widget.
The gtk_widget_set_usize() function
is used to set the size of a widget. In order to use all the
features that are provided by this function when it acts on a
window, you may want to use the
gtk_window_set_policy function. The
definition of these functions are:
void gtk_widget_set_usize (GtkWidget *widget,
gint width,
gint height);
void gtk_window_set_policy (GtkWindow *window,
gint allow_shrink,
gint allow_grow,
gint auto_shrink); |
Auto_shrink will automatically shrink
the window when the requested size of the child widgets goes
below the current size of the
window. Allow_shrink will give the user the
authorisation to make the window smaller that it should
normally be. Allow_grow will give the user
will have the ability to make the window bigger. The default
values for these parameters are:
allow_shrink = FALSE
allow_grow = TRUE
auto_shrink = FALSE |
The gtk_widget_set_usize() functions
is not the easiest way to set a window size since you cannot
decrease this window size with another call to this function
unless you call it twice, as in:
gtk_widget_set_usize(your_widget, -1, -1);
gtk_widget_set_usize(your_widget, new_x_size, new_y_size); |
Another way to set the size of and/or move a window is to use
the gdk_window_move_resize() function which
uses to work fine both to grow or to shrink the window:
gdk_window_move_resize(window->window,
x_pos, y_pos,
x_size, y_size); |
