Porady: zakotwiczenie i dokowanie formantów podrzędnych w formancie FlowLayoutPanel
Kontrolka FlowLayoutPanel obsługuje Anchor właściwości i Dock w kontrolkach podrzędnych.
Aby zakotwiczyć i zadokować kontrolki podrzędne w kontrolce FlowLayoutPanel
Utwórz kontrolkę FlowLayoutPanel w formularzu.
Width Ustaw kontrolkę FlowLayoutPanel na 300 i ustaw jej FlowDirection wartość na TopDown.
Utwórz dwie Button kontrolki i umieść je w kontrolce FlowLayoutPanel .
Width Ustaw pierwszy przycisk na 200.
Dock Ustaw właściwość drugiego przycisku na Fill.
Uwaga
Drugi przycisk zakłada taką samą szerokość jak pierwszy przycisk. Nie rozciąga się na szerokość kontrolki FlowLayoutPanel .
Dock Ustaw właściwość drugiego przycisku na
None. Powoduje to założenie oryginalnej szerokości przycisku.Anchor Ustaw właściwość drugiego przycisku na
Left, Right.Ważne
Drugi przycisk zakłada taką samą szerokość jak pierwszy przycisk. Nie rozciąga się na szerokość kontrolki FlowLayoutPanel . Jest to ogólna reguła zakotwiczenia i zadokowania w FlowLayoutPanel kontrolce: w przypadku kierunku FlowLayoutPanel przepływu pionowego kontrolka oblicza szerokość implikowanej kolumny z najszerszej kontrolki podrzędnej w kolumnie. Wszystkie inne kontrolki w tej kolumnie z właściwościami Anchor lub Dock są wyrównane lub rozciągnięte w celu dopasowania do tej implikowanej kolumny. Zachowanie działa podobnie w przypadku kierunku przepływu poziomego. Kontrolka FlowLayoutPanel oblicza wysokość dorozumianego wiersza z najwyższego formantu podrzędnego w wierszu, a wszystkie zadokowane lub zakotwiczone kontrolki podrzędne w tym wierszu są wyrównane lub mają rozmiar, aby dopasować do domniemanego wiersza.
Przykład
Na poniższej ilustracji przedstawiono cztery przyciski, które są zakotwiczone i zadokowane względem niebieskiego przycisku w obiekcie FlowLayoutPanel. Wartość FlowDirection to LeftToRight.
Na poniższej ilustracji przedstawiono cztery przyciski, które są zakotwiczone i zadokowane względem niebieskiego przycisku w obiekcie FlowLayoutPanel. Wartość FlowDirection to TopDown.
W poniższym przykładzie kodu przedstawiono różne Anchor wartości właściwości kontrolki Button w kontrolce FlowLayoutPanel .
