引言: 我用Timer元件設每五粆鐘重新更新類似ListView元件內的資料,結果每五秒執行後,畫面上的ListView元件會閃爍跳動,請問要如何解決此問題讓畫面上的 ListView元件,每五秒不會閃爍跳動

    ListView1.Items.BeginUpdate;
    try
      // 增減 ListView1.Items
    finally
      ListView1.Items.EndUpdate;
    end;

引言: Description When DoubleBuffered is false, the windowed control paints itself directly to the window. When DoubleBuffered is true, the windowed control paints itself to an in-memory bitmap that is then used to paint the window. Double buffering reduces the amount of flicker when the control repaints, but is more memory intensive. When a windowed control is a dock site and has an associated dock manager, it must be double-buffered.

就是說當 DoubleBuffered 為 TRUE 時，元件在更新畫面時，會先將要更新的部分畫在內部記憶體，等全部需要更新的部分都畫完後，再一次更新的元件上，這樣可以避免使用者看到中間更新的過程，可以減少閃爍情況，而其缺點是，會多占用一些記憶體。不過，我想這是值得的 <>沒空更新的網頁... href="http://dllee.adsldns.org">http://dllee.adsldns.org 介紹Shells,LiteStep,GeoShell....
