I want to update the panel graphics (panel will contain simple shapes like circles and rectangles) every time a button is pressed. The code would look something like this:
private void PanelGraphics()The function would be then called every time a button is pressed, and I understand button_events well enough so that's not a problem. However, I have no idea how to pull off the PanelGraphics() function, and a few links about panel_paint events didn't help me much.
{
ClearThePanel(); //empties the panel
FillThePanel(); //draws new shapes in the panel
}
You can draw to the panel by creating a graphics controller to it.
Graphics g = panel.CreateGraphics();
You can then use the Graphic class's plethora of methods to draw whatever you want to the panel
To clear the panel the easiest way is to draw a box the colour of the background to the panel
g.DrawRectangle(new Pen(panel.BackColor), new Rectangle(new Point(), panel.Size));
