Combina controles ToolStrip.
Merge(ToolStrip, String) |
Combina dois objetos ToolStrip do mesmo tipo. |
Merge(ToolStrip, ToolStrip) |
Combina dois objetos ToolStrip de tipos diferentes. |
Merge(ToolStrip, String)
Combina dois objetos ToolStrip do mesmo tipo.
public:
static bool Merge(System::Windows::Forms::ToolStrip ^ sourceToolStrip, System::String ^ targetName);
public static bool Merge (System.Windows.Forms.ToolStrip sourceToolStrip, string targetName);
static member Merge : System.Windows.Forms.ToolStrip * string -> bool
Public Shared Function Merge (sourceToolStrip As ToolStrip, targetName As String) As Boolean
Parâmetros
- sourceToolStrip
- ToolStrip
O ToolStrip a ser combinado com o ToolStrip referido pelo parâmetro targetName
.
- targetName
- String
O nome do ToolStrip que recebe o ToolStrip referido pelo parâmetro sourceToolStrip
.
Retornos
true
se a mesclagem for bem-sucedida; caso contrário, false
.
Exceções
sourceToolStrip
ou targetName
é null
.
sourceToolStrip
ou targetName
se referem ao mesmo ToolStrip.
Comentários
Use o ToolStripManager.Merge método para combinar ToolStrip objetos de tipo idêntico, como ToolStrip objetos com outros ToolStrip objetos, MenuStrip objetos com outros MenuStrip objetos e assim por diante.
Use o ToolStripManager.Merge método para combinar ToolStrip objetos de diferentes tipos.
A ToolStrip.AllowMerge propriedade deve ser definida true
para ambos os ToolStrip objetos, e os tipos de origem e de destino devem ser idênticos ou esse método retorna false
.
Nota
Se houver dois MenuStrip controles em um formulário filho MDI, a configuração IsMdiContainer para true
o formulário pai mescla o conteúdo de apenas um dos MenuStrip controles. Use Merge para mesclar o conteúdo de controles filho MenuStrip adicionais no formulário pai do MDI.
