ToolStripManager.Merge Método

Definição

Namespace:

System.Windows.Forms

Assembly:

System.Windows.Forms.dll

Combina controles ToolStrip.

Sobrecargas

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

Boolean

true se a mesclagem for bem-sucedida; caso contrário, false.

Exceções

ArgumentNullException

sourceToolStrip ou targetName é null.

ArgumentException

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.

Observação

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.

Parâmetros

sourceToolStrip

ToolStrip

O ToolStrip a ser combinado com o ToolStrip referido pelo parâmetro targetToolStrip.

Exemplos

O exemplo de código a seguir mescla itens de menu com base nas escolhas especificadas. Este exemplo faz parte de um exemplo maior disponível na visão geral da ToolStripManager classe.

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.
