Procedura: Personalizzare colori nelle applicazioni ToolStrip
È possibile personalizzare l'aspetto di ToolStrip tramite la classe ToolStripProfessionalRenderer per usare colori personalizzati.
Esempio
L'esempio di codice seguente illustra come usare una classe ToolStripProfessionalRenderer per definire colori personalizzati in fase di esecuzione.
// This code example demonstrates how to use a ProfessionalRenderer
// to define custom professional colors at runtime.
class Form2 : Form
{
public Form2()
{
// Create a new ToolStrip control.
ToolStrip ts = new ToolStrip();
// Populate the ToolStrip control.
ts.Items.Add("Apples");
ts.Items.Add("Oranges");
ts.Items.Add("Pears");
ts.Items.Add(
"Change Colors",
null,
new EventHandler(ChangeColors_Click));
// Create a new MenuStrip.
MenuStrip ms = new MenuStrip();
// Dock the MenuStrip control to the top of the form.
ms.Dock = DockStyle.Top;
// Add the top-level menu items.
ms.Items.Add("File");
ms.Items.Add("Edit");
ms.Items.Add("View");
ms.Items.Add("Window");
// Add the ToolStrip to Controls collection.
this.Controls.Add(ts);
// Add the MenuStrip control last.
// This is important for correct placement in the z-order.
this.Controls.Add(ms);
}
// This event handler is invoked when the "Change colors"
// ToolStripItem is clicked. It assigns the Renderer
// property for the ToolStrip control.
void ChangeColors_Click(object sender, EventArgs e)
{
ToolStripManager.Renderer =
new ToolStripProfessionalRenderer(new CustomProfessionalColors());
}
}
// This class defines the gradient colors for
// the MenuStrip and the ToolStrip.
class CustomProfessionalColors : ProfessionalColorTable
{
public override Color ToolStripGradientBegin
{ get { return Color.BlueViolet; } }
public override Color ToolStripGradientMiddle
{ get { return Color.CadetBlue; } }
public override Color ToolStripGradientEnd
{ get { return Color.CornflowerBlue; } }
public override Color MenuStripGradientBegin
{ get { return Color.Salmon; } }
public override Color MenuStripGradientEnd
{ get { return Color.OrangeRed; } }
}
