Fix multiple issues introduced by commit 55c2c0df9 (interactive paste):
Paste placement (diagrameventaddpaste):
- Items now load at their original XML coordinates instead of being
snapped to the cursor position, preventing jumps on initial placement
- Use delta-based movement: record the actual grid-snapped cursor
position on first mouseMoveEvent as baseline, then compute
grid-snapped deltas from there
- Bypass Diagram::snapToGrid() in moveTo() to avoid Ctrl modifier
causing pixel-snapping instead of grid-snapping
- Remove moveTo() from mouseReleaseEvent to prevent a final jump
on click
- Warp cursor to group bounding rect origin for visual feedback
Paste command (diagramcommands):
- Always clear PLC slave data (type, address, function, comment,
cross-ref, label, TC, T1-T4) on paste regardless of the
erase-label-on-copy user preference
- Block alignment (m_block_alignment / blockAlignmentUpdate) before
setElementInformations() for both slaves and non-slaves, preventing
finishAlignment() from shifting right/center-aligned text items
- Clear non-UserText items directly after setElementInformations()
for slaves as a safety net

@brief The DiagramEventAddPaste class
|
|
Paste the clipboard as a placement you can still move.
|
|
|
|
The pasted items are added straight away and follow the cursor until a
|
|
left click drops them; Escape or a right click takes them away again.
|
|
This is the same interaction as placing a new element, so a paste behaves
|
|
like every other "put something on the folio" action.
|
|
|
|
The items are the real ones from the start, not a preview: Diagram::fromXml
|
|
creates them, this class moves them, and PasteDiagramCommand is pushed only
|
|
once they are dropped. That keeps one copy of the paste logic rather than
|
|
two, and means a cancelled paste leaves nothing on the undo stack.
