[REBOL] Re: dynamic faces

From: arolls:idatam:au at: 26-Dec-2001 16:05

Here is a way using compose: lay-blk: copy [] repeat i 3 [append lay-blk [progress 12x80]] ; 3 progress bars repeat i 3 [ append lay-blk compose/deep [ button (join "modif" i) [ lpi: (to-path compose [lay pane (i)]) ; <-- lpi/data: lpi/data + 0.1 show lpi ] ] ] view lay: layout lay-blk The use of i, where it is marked with an arrow, is critical. If you change your layout, for example, to add a backdrop at the beginning, as in: lay-blk: copy [backdrop black] then the index will be incorrect. You will need to add one to it, like this: lpi: (to-path compose [lay pane (i + 1)]) Of course you could add code to track where the progress bars were inserted and add this offset at the appropriate moments later in the code. Note the use of compose/deep. It is /deep so that the reach of compose extends into sub-blocks. The calculation for lpi is within a sub-block, so we need compose/deep. Anton.
