Accessing sub-panes to change them.

If I have a face with panes and sub-panes (see below), and buttons to switch between the sub-panes. 1) How do I access the sub-panes to changes their text, data, color, etc? Button 3 below does not work? What would? 2) Is there an easy way, like 'center-face to have the sub-panes (red and blue) appear in the center of the green box? ;*****begin script***** redpane: layout [origin 0x0 space 0x0 box red 50x50] bluepane: layout [origin 0x0 space 0x0 area "original" blue 75x75] redpane/offset: 0x0 bluepane/offset: 0x0 main: layout [ button "1 red" [bx/pane: redpane show bx] button "2 blue" [bx/pane: bluepane show bx] bx: box 200x200 green button "3 change area" [ append clear bluepane/text "changed" show bluepane bx/pane: bluepane show bx ] ] view main ;*****end script*****

Hi Alan, << If I have a face with panes and sub-panes (see below), and buttons to switch between the sub-panes. 1) How do I access the sub-panes to changes their text, data, color, etc? Button 3 below does not work? What would? >> Here's a modified version of your code (watch for line wrap). There is more than one way to skin a cat but, in this case, I just gave the face you wanted to change (the area face) a name. redpane: layout [origin 0x0 space 0x0 box red 50x50] ; GSI Added name for area face. bluepane: layout [origin 0x0 space 0x0 bl-pane-area: area "original" blue 75x75] redpane/offset: 0x0 bluepane/offset: 0x0 main: layout [ button "1 red" [bx/pane: redpane show bx] button "2 blue" [bx/pane: bluepane show bx] bx: box 200x200 green button "3 change area" [ ; GSI Changed text assignment for area face. ;append clear bluepane/text "changed" bl-pane-area/text: "changed" show bluepane bx/pane: bluepane show bx ] ] view main << 2) Is there an easy way, like 'center-face to have the sub-panes (red and blue) appear in the center of the green box? >> Hmmm. I was thinking that center-face, using the /with refinement, would do the trick, but it doesn't appear to in your case. You should be able to roll your own without too much difficulty, though there may be some tricky details we can't forsee. --Gregg
