Hi, I have a question about how to obtain an effect similar to minimizing a pane in Eclipse. Let's consider the example from below. I have a ProportionalLayout because I want to fill the entire space and be able to resize the inside panes. Now, I would also like to have some way of collapsing one of the panes and have the rest resize to fill the rest of the space. It's a bit like I would need some part of a behavior from the TableLayout. Can anyone provide me with some hints in this direction? Do I need to create a new Layout? | container morph1 morph2 morph3 window | container := PanelMorph new. morph1 := PanelMorph new fillStyle: (SolidFillStyle color: Color red). morph2 := PanelMorph new fillStyle: (SolidFillStyle color: Color blue). morph3 := PanelMorph new fillStyle: (SolidFillStyle color: Color yellow). container changeProportionalLayout. container addMorph: morph1 fullFrame: (LayoutFrame fractions: (0 @ 0 corner: 1 @ 0.33)). container addMorph: morph2 fullFrame: (LayoutFrame fractions: (0 @ 0.33 corner: 1 @ 0.66)). container addMorph: morph3 fullFrame: (LayoutFrame fractions: (0 @ 0.66 corner: 1 @ 1)). container addPaneSplitters. container fillStyle: (SolidFillStyle color: Color yellow). container extent: 400@400. container openInWindow.
