Changing controls's location

Using VLE, when a control is added to a canvas, values for "x" and "y" (the relative location on the canvas) are set.

Is there a way to change these values ... for example say...if the control needs to be moved as the canvas is resized?

Thank you

Somebody else probably has better layout design advice, since I have not used the VLE that much. But if you are concerned about resizing, you might want to change your layout from using a canvas. You can make a new layout with a different container as the outermost container, such as a VBox. Then you can nest other things inside of that, and it will resize more flexibly. You could put a canvas inside of some of these other containers.

Just to clarify -

Resizing the Canvas works fine.. and through the resize-action proc I am able to change some of the properties of the controls on the Canvas..

For example, I am able to change the 'width' of a control from the resize-action proc.

Question is - how to re-position the controls on the canvas, based on canvas.actual-width and canvas.actual-height ? Can we set 'x' and 'y' at run-time?

Thank you

Canvas.add method accepts x = and y = keyword parameters, these are used to determine the position of a graphic on the canvas.

Thanks for the information.

Could reposition the controls using canvas.move-to-xy and canvas.shift-to-xy methods.
