當MCU_timer_Tick()被調用時,我想調用OnPaint()。 我該怎麼辦?如何將EventArgs轉換爲PaintEventArgs,C#
private void MCU_timer_Tick(object sender, EventArgs e)
{
...
}
protected override void OnPaint(PaintEventArgs e)
{
Graphics g = e.Graphics;
int width = 30;
int x, y;
x = 150;
y = 530;
double color_max;
color_max = 255;
SolidBrush aBrush_1 =
new SolidBrush(Color.FromArgb(100, 255,
(int)(255 * color_map[0]/color_max), 0)); //color_map[0] is real value
g.FillEllipse(aBrush_1, x-100, y, width * 2, width);
