Maximieren Sie die Zerstörungs -Setdragregionen einer CustomTitlebar mit Tabview ⇐ C#

[Anonymous]

Ich habe Probleme mit der SetDRagRegion -Methode
Ich starte den Debugger. Alle funktionieren feine Bildunterschriften und TabvieItem sind nicht draggbar
Aber wenn ich mein Fenster maximiere, kann ich mich mit dem TabvieItem maximieren und den Schäbchen, der das TapvieItem aus dem Fenster addiere, das Schaltwechsel addiere. Aber das möchte ich nicht < /p>
Mein TabviewControl VisualTree < /p>

Code: Select all

< /code>
My UserWindow (MainWindow) VisualTree < /p>

Code behind: alle mthodsinclude SertDragRegion
private void MyUserWindow_SizeChanged(object sender, WindowSizeChangedEventArgs args)

this.MyCaptionsRegion.OnWindowStateChanged();

i Testet auch, wenn die korrekte Größe berechnet
Start:
[setDaggablearea] Grenzen: x = 97, y = 0, w = 1327, H = 40
[setDaggableara] scaled rect: x = 97, y = 0, w = 1327, H = 40 < /p> < /p>
[SetDraggableArea] Bounds: X=97, Y=0, W=1823, H=40
[SetDraggableArea] Scaled Rect: X=97, Y=0, W=1823, H=40
After restoring back:
[SetDraggableArea] Bounds: X=97, Y=0, W=1327, H=40
[SetDaggablearea] scaled rct: x = 97, y = 0, w = 1327, H = 40 < /p>
