How to set the minimum window size according to its contents in JavaFX?

Question

To statically set the minimum window size to a frame of 100x100 pixels in JavaFX 2.2, you should use:

 stage.setMinWidth(100); stage.setMinHeight(100); 

Suppose we don’t want to set a fixed minimum size, but we want the window to be resized to a minimum size, and all its contents (buttons, text fields, etc.) are still fully visible. How do we do this?

Answer 1

You can try using stage.minWidthProperty (). bind (... Binding expression here ...);

The difficulty, of course, is to define a binding expression ... it should depend on all your components, but still it should work.

Resizing children will change the binding expression and change the minWidthProperty property on your scene.

Answer 2

I suggest you read the javadoc Pane , Region and possibly Group nodes. About how they plan and resize their children. In principle, if you do not set a preferred panel size, then by default it will be calculated according to its contents. Also see the Window.sizeToScene () method .
