Current solution to force a redrawing of the terrain-selection grid
|
|
when undoing/redoing changes in the editor.
|
|
This only triggers a simple redraw of the grid, so only use it in
|
|
conjunction with actual data changes which deform the grid.
|
|
|
|
Please note that this command needs to be put onto the QUndoStack twice:
|
|
at the start and at the end of the related terrain manipulation.
|
|
This makes sure that the grid is always updated after all changes have
|
|
been undone or redone -- but it also means that the selection is redrawn
|
|
once at the beginning of either action. Future refinement may solve that.
