当RectangleShape调整大小时停止闪烁 [英] Stopping flickering when RectangleShape resizes

问题描述

您好，



我正在制作一个自定义进度条，其中有灰色背景（2），进度矩形（1）为蓝色。为了显示正在进行的进度，进度矩形的宽度增加（见图表）。

 _____________________ 
 | | | 
 |  1  |  - >  2  | 
 | ____________ | ________ | 

问题是，即使使用以下代码，进度矩形也会闪烁：

 我 .SetStyle（ControlStyles.UserPaint， True  ）
  Me  .SetStyle（ControlStyles.AllPaintingInWmPaint， True ）
 我 .SetStyle（ControlStyles.DoubleBuffer， True ）

进度矩形的宽度被编码为在间隔100ms的定时器上增加1到400.



请帮忙。我找不到任何其他答案，我不想创建一个flash动画。

你能告诉我们方法吗重写OnPaint（）？

Dim g as graphics = me.creategraphics - > e.graphics ...

Hello,

I'm making a custom progressbar where there is a gray background (2) and the progress rectangle (1) is blue. To show progress being made, the progress rectangle increases in width (see diagram).

The problem is that even with the following code, the progress rectangle flickers:

Me.SetStyle(ControlStyles.UserPaint, True)
Me.SetStyle(ControlStyles.AllPaintingInWmPaint, True)
Me.SetStyle(ControlStyles.DoubleBuffer, True)

The progress rectangle's width is coded to increase by 1 up to 400 on a timer with the interval 100ms.

Please help. I can't find any other answers and I don't want to have to create a flash animation.

Could you show us the method overriding OnPaint()?

Dim g as graphics= me.creategraphics --> e.graphics...
