如何给combo控件添加自定义图片？（已解决）
本帖最后由 nmgwddj 于 2011-11-30 13:56 编辑如下图，可以将自己的jpg或者bmp图片显示在combo控件上。我自己试了试_GUIImageList_AddBitmap还是添加不上，论坛搜索了以下貌似没有类似例子。
这个貌似需要加上 $CBS_OWNERDRAWVARIABLE 等样式，自绘 Combo~

我得先看看，够我消化一段时间了，不要笑话我，不好意思{:face (396):} 学习了，谢谢！！！ 回复 4# 3mile
学习了，正在学自绘 可以使用bmp图片（或转成bmp图片），然后 _GUIImageList_AddBitmap() 就不用自绘了，也简单多了~ 用了皮肤估计也不起作用吧？ 回复 8# afan
果断可以了，因为之前一系列错乱，竟然 @ScriptDir & '\Test.bmp' 里面少了个“\”。导致之前实验不成功。
不过还是很感谢3mile的列子！
