矩形以Windows形式闪烁 [英] Rectangle to blink in windows form

问题描述

当我从列表视图中选择矩形时，如何使矩形以Windows形式闪烁?

How can i make the rectangle blink in windows form when i select it from a list view?

推荐答案

在这里...什么样的矩形?这是Microsoft.VisualBasic.PowerPack的RectangleShape吗?还是您以编程方式绘制它?

无论哪种方式，我都会使用一个计时器.只需将间隔设置为您希望其闪烁"的速度即可.然后在Timer_Tick上，使其闪烁.

如果是RectangleShape，只需运行

Well, there''s not a lot to go on here...what kind of rectangle? Is this the RectangleShape from Microsoft.VisualBasic.PowerPack? Or are you drawing it programmatically?

Either way, I would use a Timer. Just set the Interval to however quickly you want it to "blink". Then on the Timer_Tick, blink it.

If it''s a RectangleShape, just run

RectangleShape1.Visible = !RectangleShape1.Visible;

如果要绘制，则必须做更多的工作……使矩形的区域无效，然后根据您上次所做的操作绘制或不绘制.

If you''re drawing it, then you''ll have to do a little more...invalidating the region of the rectangle and then either drawing or not drawing based on what you did last time.
