Can you write down a state chain, please? > Give an example? Sure. Let's say I have an image with the following layer tree: * - G1 * - - L1 * - - G2 * - - - L2 * - - - L3 * - L4 * - G3 * - - L5 * - - L6 If I Shift+Click on L3, GIMP should toggle between "all items" and "ONLY item L3". Specifically: 1 - The path to the clicked item in this case is "G1 -> G2 -> L3". Therefore, G1, G2, and L3 shall all be made visible. 2 - All direct siblings to any of G1, G2, or L3 shall be made non-visible. This means: 3a - On the top level, G1's siblings are L4 and G3. L4 and G3 shall be hidden. 3b - G2 has one sibling: L1. L1 shall be hidden. 3c - L3 has one sibling: L2. L2 shall be hidden. 4 - L5 and L6, the descendants of G3, are not relevant and shall not be affected -- we already hid G3 and that is sufficient. 5 - L3 is now the only visible item in the entire image. 6 - If I Shift+Click again, steps 2 and 3 are repeated, but with siblings made visible. Or say I Shift+Click on G2, GIMP should toggle between "all items" and "ONLY item G2": 1 - The path in this case is just "G1 -> G2". Even though G2 is a group containing child items (L2 and L3), those items are NOT of interest right now because I am acting on G2 as a whole. 2 - G1 and G2 shall both be made visible. 3 - Any siblings to G1 or G2 shall be made hidden: 3a - L4 and G3 are siblings to G1; they shall be hidden. 3b - L2 is sibling to G2; it shall be hidden. 4 - G2 is now the only visible item in the entire image. 5 - If I Shift+Click again, steps 2 and 3 are repeated, but with all siblings made visible. Note what happens if I click on a top-level item, say, L4: 1 - The path is now simply "L4". L4 shall be the only item made visible. 2 - All direct siblings of L4 (G1 and G3) shall be made hidden. 3 - Any items inside G1 and G3 are NOT of interest and shall NOT be individually affected. 4 - L4 is now the only item actually visible in the entire image. 5 - If I Shift+Click again, repeat step 2 but with siblings made visible. This last case neatly duplicates our current behavior in 2.8.0 by affecting only top-level layers. -- Stratadrake strata_ranger hotmail com -------------------- Numbers may not lie, but neither do they tell the whole truth. |
