Contoh

Contoh kode berikut menunjukkan cara menggunakan properti untuk penyajian ContentRectangle kustom. Contoh kode ini adalah bagian dari contoh yang lebih besar yang disediakan untuk ToolStripItem kelas .

// 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.
