build I20041013 - layout out a perspective in a single column as follows: view A view B editor area - grab the sash at the bottom of view B and drag it down - the top of view B moves down as well This is unexpected. Normally dragging a sash should only affect the adjacent edges of the two parts on either side of the sash. I suspect this is due to the editor area changing size.
More info. It seems to depend on how the view was dropped above the editor area. Initial state: - Navigator and Tasks in same folder - editor area underneath Scenario 1: - drag Tasks to the bottom of its folder (drag cursor pointing down) - drag the sash between the Tasks view and the editor area - it moves the top as well Scenario 2 (starting from Initial state): - drag Tasks to the top of the editor area (drag cursor pointing up) - drag the sash between the Tasks view and the editor area - it does not move the top as well - drag the sash between the Tasks view and the Navigator view - it does not move the top as well - it keeps the Tasks view the same size, but resizes the editor area instead
What is happening right now is that the underlying implementation (a KD tree) is being revealed. The sash on one side of the view will always be a parent of the sash on the other side. When dragging the parent node, its changes will affect the child node and there will be no limit on how far you can drag the sash. When dragging the child node, the changes will only affect adjacent parts but the sash cannot be dragged farther once the view's minimum size is reached. This is easy to observe if you align 4 or 5 views in a column. I agree that this should be changed. I believe the ideal behavior would be as follows: - Resizing a sash only affects adjacent views until the adjacent views reach minimum size. - Once an adjacent view reaches its minimum size, attempting to shrink it further will start to push the next view over (reducing its size up to the minimum). - If there are no more views whose size can be reduced, the sash will not be allowed to move further in that direction. Note: this is an old problem. It was much more severe in Eclipse 2.1, when resizing views on one side of the editor area would affect the size of views on the other side of the editor area.
+1 for the desired behaviour you describe.
This seeems to be working in Eclipse 3.5.
