Source:: ButtonRenderer.cs

Draws a button control in the specified state and bounds.

public:
 static void DrawButton(System::Drawing::Graphics ^ g, System::Drawing::Rectangle bounds, System::Windows::Forms::VisualStyles::PushButtonState state);

public static void DrawButton (System.Drawing.Graphics g, System.Drawing.Rectangle bounds, System.Windows.Forms.VisualStyles.PushButtonState state);

static member DrawButton : System.Drawing.Graphics * System.Drawing.Rectangle * System.Windows.Forms.VisualStyles.PushButtonState -> unit

Public Shared Sub DrawButton (g As Graphics, bounds As Rectangle, state As PushButtonState)

Parameters

g: Graphics

The Graphics used to draw the button.

bounds: Rectangle

The Rectangle that specifies the bounds of the button.

state: PushButtonState

One of the PushButtonState values that specifies the visual state of the button.

Remarks

If visual styles are enabled in the operating system and visual styles are applied to the current application, this method will draw the button with the current visual style. Otherwise, it will draw the button with the classic Windows style.

Examples

The following code example uses the DrawButton(Graphics, Rectangle, String, Font, Boolean, PushButtonState) method in a custom control's OnPaint method to draw a button in the state determined by the location of the mouse pointer. This code example is part of a larger example provided for the ButtonRenderer class.

    // Draw the large or small button, depending on the current state.

            // are disabled, because DrawParentBackground will only paint
