Delphi TStringGrid闪烁 [英] Delphi TStringGrid Flicker

问题描述

我从CSV文件@运行时向字符串网格添加了多行，但是当它被越来越多的时候，StringGrid似乎闪烁了很多，我推测会有一个beginupadate / Endupdate命令来阻止它。但是我找不到它。当更新网格ID时，是否有另一种方法来停止闪烁。

解决方案

$ b我使用 WM_SETREDRAW 。例如：

  ... 
 StringGrid1.Perform（WM_SETREDRAW，0，0）; 
 try 
 // StringGrid1用这里的数据填充
 finally 
 StringGrid1.Perform（WM_SETREDRAW，1，0）; 
 StringGrid1.Invalidate; //重要！所有
结束后强制重绘; 
 ... 
  

I am adding multiple rows to a string grid from a CSV file @ runtime, However the StringGrid seems to flicker lots when it is being upadated, I presumed there would be a beginupadate / Endupdate command to stop this. However I cannot find it. Is there another way to stop the flicker when the grid id being updated.

解决方案

Better late than never... I use WM_SETREDRAW. For example:

...
StringGrid1.Perform(WM_SETREDRAW, 0, 0);
try
  // StringGrid1 is populated with the data here 
finally
  StringGrid1.Perform(WM_SETREDRAW, 1, 0);
  StringGrid1.Invalidate; // important! to force repaint after all
end;
...
