Hello,
I am using a TDBPlanner in timeline-mode with a day/hour-timeline on the X-axis (sidebar) and positions on the Y-axis (header, planner is inverted).
When holding SHIFT I can select multiple cells in one position. With DisjunctSelect I can also hold STRG + SHIFT to successively select an area of cells across multiple positions.
I would additionally really like to enable the user to hold SHIFT and then select the whole rectangle of cells across positions with just two clicks. This doesn't seem to work at least by default. When I hold SHIFT, select one cell and then another cell in a different position, I can see the whole rectangle in between flicker in the selected-color for a short moment, but then afterwards only the cells in the position of the second selected cell are marked as selected.
I am quite certain that I would be able to manually implement the desired behavior by using a combination of events like KeyDown, BkgProp etc, but before I do that I would like to ask whether there is a simpler, less error-prone way to achieve that. Maybe I have simply overlooked an attribute or misconfigured the planner? I haven't found anything in that regard.
