关于汽泡式ToolTiptext的问题已困扰我好几天，请大家帮忙！！！！！！！！

[cmt123]

我有一段原码，可以实现汽泡式ToolTiptext，字体颜色、背景等都可以实现，但字体大小、字型等不能实现！请大家帮忙！！我的代码如下：

不知道CREATEFONT+GETDC+SelectObject行不行

这个90m的大代码里有tooltip类

以下下载到枕善居：

在Listview中如果内容太长，需要调整列宽才能看完整信息。现在用这个气泡提示信息，就不要调整列宽了。
即时在气泡中显示内容。

这些程序都没有没有对汽泡式ToolTiptext的字体大小、字型设置！

[balloonman2002]

我后来查了一下资料，wm_setfont可以更改tooltip的字体，这在你代码中已经有了
