在StatusBar中重绘ProgressBar [英] Redraw ProgressBar in StatusBar
问题描述
当我在进度条运行时调整窗体大小（放大）
矩形图形不会到达矩形的末尾？
我有一个带有一个按钮的表单，一个状态栏有三个状态栏面板
这是帮助的代码
那里有什么问题？

我尝试了你的代码，但我无法重现这个问题。我可以在另一个线程中绘制
面板的过程中调整窗体大小
（调整停靠状态栏的大小）（调整面板大小），面板总是完全填充。 />

重新产生我得到的错误：
1）启动应用程序（不应该最大化） - （如果全屏启动
没问题）
2）按下按钮启动进度条
3）当进度条递增时，抓住表格的右侧
广泛拉伸表格然后在进度条前释放鼠标
停止。进度条计数器仍然应该递增（指示状态栏面板的宽度
），但绘图不再是他的
原始最大宽度而不是结束小组。
感谢您的帮助，如果您发现任何内容

我知道这对我们没有帮助你但是我想请你帮我做一个
进度条吧。我需要制作一个弹出进度条（在表格上），这将显示文件下载的进度。
你可以帮助我。
谢谢，

I tried your code but I can not reproduce the problem. I can resize the form
(resizing the docked statusbar (resizing the panel)) during painting the
panel in the other thread and the panel is always filled completely.

To rreproduce the error that I got:
1) launch the application (should not be maximized) - (if launch full screen
no problem)
2) press the button to start the progress bar
3) while the progress bar is incrementing, grab the right side of the form
to strech widely the form then release the mouse before the progressbar
stop. The progress bar counter should still increment (indicating the width
of the statusbarpanel) but the drawing is not going anyfurther then his
original maximum width instead of going to the end of the panel.
Thank you for your help if you find anything
