Exemples

L’exemple de code suivant montre comment utiliser la propriété pour le ContentRectangle rendu personnalisé. Cet exemple de code fait partie d’un exemple plus grand fourni pour la ToolStripItem classe.

// This utility method computes the layout of the 
// RolloverItem control's image area and the text area.
// For brevity, only the following settings are 
// supported:
//
// ToolStripTextDirection.Horizontal
// TextImageRelation.ImageBeforeText 
// TextImageRelation.ImageBeforeText
// 
// It would not be difficult to support vertical text
// directions and other image/text relationships.
