Objective
By right, the default size of a GtkButton corresponds to the size of its label. However, as you have seen in the previous few examples, it is always displayed extending across the entire width of the screen as shown below:
In this example, we will see how to display a button in its default size.
Overview
- First create a GtkButton.
- Then create a GtkHBox.
- Pack the button inside the hbox, set
expand=false.
- Then pack the hbox inside the vbox, also set
expand=false.

$window->set_size_request(200, 100);
$vbox = new GtkVBox();
$window->add($vbox);
$button = new GtkButton('button label');
$hbox = new GtkHBox();
$hbox->pack_start($button, false); // note 1

Explanation
expand=false will ensure that the button does not expand horizontally in the hbox.expand=false will ensure that the button does not expand vertically in the vbox.
As a result, the button is displayed in its default size – at the top, left corner of the window.
