blocks|key|5078767|text|几年前，我在TurboPower+Orpheus+ComboBox中添加了主题支持。看看{$IFDEF+VERSION2010}...{$ENDIF}部分中的代码。这应该会让你对所需要的东西有一个很好的了解。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|5078768|entityMap|0|LINK|mutability|MUTABLE|url|https://sourceforge.net/p/tporpheus/code/HEAD/tree/trunk/source/ovccmbx.pas^0|6|R|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

I added theming support to the <a href="https://sourceforge.net/p/tporpheus/code/HEAD/tree/trunk/source/ovccmbx.pas" rel="nofollow">TurboPower Orpheus ComboBox</a> a couple of years ago. Take a look at the code inside the {$IFDEF VERSION2010}...{$ENDIF} sections. That should give you a pretty good idea about what is needed.

I fixed it in drawitem 

<pre><code>procedure Tfrmxxx.cbTypeDrawItem(Control: TWinControl; Index: Integer;
 Rect: TRect; State: TOwnerDrawState);
begin
 with (Control as TCombobox).Canvas do
 begin
 if odSelected in State then
 Brush.Color := StyleServices.GetSystemColor(clHighlight);// $00FFD2A6;

 FillRect(Rect);
 TextOut(Rect.Left, Rect.Top, (Control as TCombobox).Items[Index]);
 if odFocused In State then
 begin
 Brush.Color := (Control as TCombobox).Color;
 DrawFocusRect(Rect);
 end;
 end;
end;
</code></pre>

A very easy way to show different string values than the <a href="http://docwiki.embarcadero.com/Libraries/en/Vcl.StdCtrls.TCustomCombo.Items" rel="nofollow noreferrer">Items</a> is to set the <a href="http://docwiki.embarcadero.com/Libraries/en/Vcl.StdCtrls.TCustomComboBox.Style" rel="nofollow noreferrer">Style</a> property from <a href="http://docwiki.embarcadero.com/Libraries/en/Vcl.StdCtrls.TComboBoxStyle" rel="nofollow noreferrer"><code>csDropDown</code> to <code>csOwnerDrawFixed</code></a> as <a href="https://stackoverflow.com/users/282848/andreas-rejbrand">Andreas Rejbrand</a> has <a href="https://stackoverflow.com/a/3022956/29290">answered a few years ago</a>.

The thing is: as soon as you do that, you loose Windows Theming support. 
The same limitation applies to using <code>csOwnerDrawVariable</code>

These two <code>Style</code> values get translated into adding the <code>CBS_OWNERDRAWFIXED</code> or <code>CBS_OWNERDRAWVARIABLE</code> (in addition to <code>CBS_DROPDOWNLIST</code>) <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/bb775796" rel="nofollow noreferrer">styles</a> of the Windows <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/aa380889" rel="nofollow noreferrer">COMBOBOX control</a>.

In turn, <code>CBS_OWNERDRAWFIXED</code> or <code>CBS_OWNERDRAWVARIABLE</code> cause you to <a href="https://stackoverflow.com/questions/10031621/cbs-dropdownlist-combo-fails-to-respond-to-wm-ctlcolor-under-windows-ux-themi">instantly loose the Windows theming support</a>.

When you do full custom painting <a href="http://www.codeforge.cn/read/9851/XColorPickerXP.cpp__html" rel="nofollow noreferrer">like a colour picker</a>, that is all fine. But when you only want to replace the drawn text, it is not.

<a href="https://stackoverflow.com/questions/2125090/ownerdraw-combobox-is-not-styled-anymore">The Windows COMBOBOX control does not seem to have a way around this</a>, so I'm wondering: how can you simulate the Windows theming from Delphi?

I assume it has to do with <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/bb773289" rel="nofollow noreferrer">DrawThemedBackground</a>, but it has been a while since I've done serious Delphi Control work, so any pointers on how to get started there are fine too (even if they invalidate my assumption).

How to simulate Windows Theme behaviour when TComboBox uses csOwnerDrawFixed or csOwnerDrawVariable?
