Removing an ugly border

Me artist. Me like pretty. Me say it look better, it be better. Ook. Ook.

So...what you are saying is that I'd have to roll my own splitter? ST_SplitterWnd is probably a better codebase to start from and then just override the painting code from CSplitterWnd in ST_SplitterWnd but that would really only be necessary for the case where someone wants to set an alternate style. The default works pretty well for most cases.

:laugh: Overriding the painting part is fairly easy. It's all the calculations for repositioning the view panes that are based on the 3D border that are the problem! CSplitterWnd::OnDrawSplitter() overridable looks interesting... If you do all that work, I'll gladly "test" it for you for free :) Mark

I'm still looking at the CSplitterWnd code. There's a few handy undocumented overridables. May not be as much work as I thought... I'm going to try a bit and see what happens. Opening the can of worms...

Here's a custom CSplitterWnd class - all I changed was the constructor :) Needs a little work but getting rid of the fat 2 pixel border helps. I'd like to draw them more subtle like Visual Studios... (I removed themes for these screenshots) Before (CSplitterWnd)[^] After (CMySplitterWnd)[^]

class CMySplitterWnd : public CSplitterWnd
{
public:
CMySplitterWnd();
};

CMySplitterWnd::CMySplitterWnd() : CSplitterWnd()
{
// from CSplitterWnd
// // default splitter box/bar sizes (includes borders)
// m_cxSplitter = m_cySplitter = 3 + 2 + 2;
// m_cxBorderShare = m_cyBorderShare = 0;
// m_cxSplitterGap = m_cySplitterGap = 3 + 2 + 2;
// m_cxBorder = m_cyBorder = 2;

// default splitter box/bar sizes (includes borders)
m_cxSplitter = m_cySplitter = 3;
m_cxBorderShare = m_cyBorderShare = 0;
m_cxSplitterGap = m_cySplitterGap = 3;
m_cxBorder = m_cyBorder = 0;
}

These settings seem more pleasing... m_cxSplitter = m_cySplitter = 3 + 1 + 1; m_cxBorderShare = m_cyBorderShare = 0; m_cxSplitterGap = m_cySplitterGap = 3 + 1 + 1; m_cxBorder = m_cyBorder = 1; Here's a screenshot[^] -- modified at 21:03 Wednesday 21st February, 2007

Not exactly the effect I'm going after. It affects both sides of the splitter. I want to control just the "client edge" drawing of one specific view. In this case, the code should only affect just one side of the splitter (top part). Figure how how to affect the drawing of a single side of a splitter and you'll probably have code worthy of a CP article on your hands.

[Mark Salsbery]

That may be easy. There's a documented override for the drawing. I'll try in the morning (11:17pm here :)) It looks like I need something similar with a splitter on a tab control. The top line of the splitter pane box messes up the indication of which tab is selected. Mark

Get anywhere with that?

[Mark Salsbery]

I'm back on it - got totally sidetracked on some emailed code yesterday :) I shall return...

Ok. So far I can control... Splitter width 3D Border width (0,1,2(default)) Which border sides are drawn All the colors of the drawn border sides (if thickness 2, 2 colors each) Face color of splitter bar All border and face colors of the splitter box (shown/used on dynamic splitters) Useful?

:doh: That would be tough - I need to investigate that further. Still finishing it up in article-worthy (hopefully) fashion. Mark

Interesting. I'd probably have to see a demo app. in action. Or get sleep. One of the two anyway.

Hmm...maybe it can be faked by setting border width to 0 and then setting WS_EX_CLIENTEDGE on each view EXCEPT the views that authors don't want. Would that work? I'll try it sometime in the next two days with ST_SplitterWnd, but it would be nice to know if it will work up front before I burn a couple hours trying.

Good idea. I'll send the code tomorrow am - it's easy enough to test - it's derived from CSplitterWnd.

Anything happening with this? I've been busy with other projects and haven't had time to try anything out.
