Currently the update of propsheet is delayed to prevent frequent updates from keyboard navigation. It should skip the delay for the case of mouse selection (if distinguishable) or shorten the delay to net be noticeable while using mouse (50ms should suffice to eliminate keyboard updates).
It is especially visible in form editor, where user selects the component just because of inspecting its properties.
*** Issue 14327 has been marked as a duplicate of this issue. ***
So, are you sure that those 250 ms is the real problem (and not the #14327)?
I think so, at least for the form editor usage, where it is connected with complexity of the created sheets. If we manage to recognize mouse generated node change, we'll get 250ms for free, if not, we can still get 180ms for free by reducing the delay to 70ms while removing the frequent on-time update from the keyboard navigation (>15chars/s autorepeat). And the percentual gain will be bigger on faster machines. Ask HIE for their response requirements. Issue 14327 should be fixed too, but it is only part of the effort.
after those issues 14327,21706,21743 being fixed now the update of property sheet is fast enough. Each module still can improve something on its own by speeding the generation of property sets.
