Custom Control Button with different regions

Mar 6th, 2006

Hi,

Im trying to create a button that will perform different functions depending on what part of the button you click. The button will be a diamond shape with six different regions on it that will perform different actions (play, pause, volume up/down etc). Does anyone know any good sites where I can get help with this as Im not sure where to start.

Thanks.

I suggest you create a control with 4 seperate buttons for each function, but then draw them together so it looks like one button.

below is code that makes a button look like a circle. this should be the onPaint function for the button. it shouldnt be to difficult to edit this to work for you

 C# Syntax (Toggle Plain Text) 
		// This method will change the square button to a circular button by 
		// creating a new circle-shaped GraphicsPath object and setting it 
		// to the RoundButton objects region.
		private void roundButton_Paint(object sender, System.Windows.Forms.PaintEventArgs e)
		{
 
			System.Windows.Forms.Button tButton = (System.Windows.Forms.Button)sender;
 
 
			System.Drawing.Drawing2D.GraphicsPath buttonPath = 
				new System.Drawing.Drawing2D.GraphicsPath();
 
 
			// Set a new rectangle to the same size as the button's 
			// ClientRectangle property.
			System.Drawing.Rectangle newRectangle = tButton.ClientRectangle;
 
			// Decrease the size of the rectangle.
			newRectangle.Inflate(-10, -10);
 
			// Draw the button's border.
			e.Graphics.DrawEllipse(System.Drawing.Pens.Black, newRectangle);
 
			// Increase the size of the rectangle to include the border.
			newRectangle.Inflate( 1,  1);
 
 
			// Create a circle within the new rectangle.
			buttonPath.AddEllipse(newRectangle);
 
			// Set the button's Region property to the newly created 
			// circle region.
			tButton.Region = new System.Drawing.Region(buttonPath);
 
		}
		// This method will change the square button to a circular button by 
		// creating a new circle-shaped GraphicsPath object and setting it 
		// to the RoundButton objects region.

			System.Windows.Forms.Button tButton = (System.Windows.Forms.Button)sender;
			

			System.Drawing.Drawing2D.GraphicsPath buttonPath = 
				new System.Drawing.Drawing2D.GraphicsPath();

			
			// Set a new rectangle to the same size as the button's 
			// ClientRectangle property.
			System.Drawing.Rectangle newRectangle = tButton.ClientRectangle;
			
			// Decrease the size of the rectangle.
			newRectangle.Inflate(-10, -10);
        
			// Draw the button's border.
			e.Graphics.DrawEllipse(System.Drawing.Pens.Black, newRectangle);

			// Increase the size of the rectangle to include the border.
			newRectangle.Inflate( 1,  1);


			// Create a circle within the new rectangle.
			buttonPath.AddEllipse(newRectangle);
                
			// Set the button's Region property to the newly created 
			// circle region.
			tButton.Region = new System.Drawing.Region(buttonPath);
