Hi Igor, I like the fraction/offset model from SmalltalkMT. I once ported it to Squeak. This gives you full control on absolute and relative positioning within the bounds of the parent and controls resizing behavior. Only 4 parameters for anything you need ...
Example: self addMorph: startButton to: pane offset: #(0 0 101 20) fractions: #(0 0 0 0). means the button starts top left at x1=0, y1=0 with the bottom right corner at x2=101 and y2=20. There is no fraction given - so we have absolute positioning. If you give a fraction you tell the system that for instance a subpane should always start at 30% from the side of a parents box. -> relative positions with resizing. If you additionally give an offset you can define that there is an additional absolute margin after the 30%. With a negative offset you can absolute position the control/submorph on the other side of the 30% virtual line. With fractions: #(0 0 1 1 ) which means 100% the control will fill the parent and will fully resize with it. Smalltalk MT used 1000 for 100% of the parents area, but thats only a definition. Have a look at the project "Sandcastle" on Squeaksource, especially Sandcastle-tbn.9.mcz. SCApplicationWindow (a subclass of SystemWindow here) provides a few methods to support this dynamic layout and its subclass SCWelcomeWindow shows how you can use it. Hope this helps Bye T. -- Aufgepasst: Sind Ihre Daten beim Online-Banking auch optimal geschützt?
