Exemplos
O exemplo de código a seguir demonstra como usar as Pushedpropriedades e PartialPush . Para executar o exemplo, cole o código a seguir em um formulário que contém um RichTextBox controle chamado RichTextBox1
. Chame o InitializeToolBar
método no construtor ou Load
método do formulário.

Comentários
Quando PartialPush é definido como true
, o botão da barra de ferramentas parece ter seu rosto esmaecido. Essa aparência é diferente da aparência esmaecida quando a Enabled propriedade é definida false
como, uma vez que a aparência de push parcial dá uma neblina para toda a face do botão. Essa propriedade não tem efeito, a menos que o ToolBarButtonStyle esteja definido como ToggleButton
.
