actually what it looks like (does this for horizontal and vertical resize) is that it simply doesn't re-draw the actual splitter (the black bar) until you resize or otherwise invalidate the pane content.

Hi,
Can't reproduce it with our samples :( What version you previously used ?
Do you see it only while first running form ? Try add m_paneManager.RedrawPanes(); in the end of OnCreate.

Hi
I previously ran 13.2.0, and every version back to 11.something, and never noticed it before. It happens whenever I resize. I'm pretty sure it's new after 13.2 (i.e. I don't think it happened in 13.2). |

Hi, maybe you can cut your project and send to support to test ?
Do you have m_paneManager.UseSplitterTracker(TRUE) or FALSE ?

Hi. Unfortunately the project is very complex (lots of DLLs building the overall UI), so it's not simple to cut it out to send. However, I have some more information.
Basically the problem looks like it isn't drawing the splitter (black bar). This happens on a move of the splitter position. It does then draw it whenever a) app loses focus b) resize of app frame I also got a partial draw of the splitter bar when some app underneath my app redrew an area. This is on Windows 7 64 bit, but the app is a 32 bit app. It doesn't happen when remote desktopped to that machine, only when logged in locally. What you see in the problem area is a slice of the window that was on the side of the splitter that the splitter was moved towards. E.g. if you have a vertical splitter and move it to the right, you see a thin slice of what is the left-most part of the right pane. I'll recheck to see if this happens on 13.2.0 and get back to you.

I rebuilt everything (about 40 projects - thank heavens for incredibuild!!!) on 13.2.0.
It looks like the problem still is there, but doesn't happen as often. E.g. it's less likely. On 13.2.1, it happens every move of the splitter. On 13.2.0 not so often. I guess this is why I didn't notice it before. |

actually with the partial draws, depending on where I move the mouse around, I can get different bits of it to draw in.
This makes me think the rectangle for the splitter isn't being properly added to the window update region, and so the painting is being clipped or something. |

Hi,
Please try to catch it with our samples. Try set same properties for DockingPane in sample as you have in your app.
Thanks

Hi
sorry, I didn't try to repro yet with the samples. However, some more interesting information. I have a tree on the left of my splitter in a docking pane. On the RHS I have the client area. If the client area contains a report control the problem doesn't occur. Maybe the report control invalidates itself again on resize? |

Hi,
I think it can be application specific thing - maybe you constantly process messages and don't give chance for dockingPane catch MW_PAINT and draw it. or something like that. Check CPU load.
I don't think it will be too difficult copy project, cut its functionality and send to support to test. sorry I don't see another way how we can help here.

Hi
CPU load is very small. This is on an i7. There are thousands of files in the project, and the UI framework loads DLLs that are sent over the wire from our back end. So it would take me about a week to strip everything out. I will try to debug myself - anywhere I should look first? |

Hi Oleg It's getting called twice on each move. However I'm pretty certain it's something to do with management of the update region, since sometimes only part of the splitter is actually redrawn. In fact it can be patchy, like several chunks of it drawn, but not the whole thing. It gets properly drawn whenever the focused docking pane is changed (e.g. click on another docking pane). I tried calling invalidate on the splitter window after the tracking, but that didn't help either. I think there's something funny going on with the window update regions or clipping regions. |

I can confirm it's an update region issue.
When it's showing the problem, I can drag another small application frame over it (like the eraser in mspaint), and it draws only under where the application has been dragged over. So the bar isn't being added to the update region. As for why Invalidate() doesn't fix this...? |

Hi,
I still think its some of you attached window is reason. Maybe in its drawing routine it set clip region or something.
Try go to AttachWindow handler and don't attach some windows (all or single) and check if you still see it.

the child are of the pane manager I don't think we attach the windows to it.
I have a lot of windows which I put in that child area, and swap between them depending on the selection from a navigation tree control. I tried attaching and detaching them from the pane manager before in the past and it had all sorts of problems. So, the window on the RHS isn't a child of the pane manager. Actually I can't find a window in Spy++ that is the pane manager - only the dockingpanesplitter and dockingpanetabbedcontainer windows. The "child" area is a sibling of those. |

With aero off, it doesn't do it any more. |

actually, looks like it still does do it with aero off.
And the funny thing is, it does this for MSDev 2008 as well! So I guess this is MS functionality that is being replicated :) Wonder if it could be my OS? We had some other issues with missing WM_SIZE messages. |

looks like something to do with desktop composition (performance visual effect settings).
If I turn this off, the problem goes away. Funny that MSDev 2008 suffers from the same problem. Problem is it all looks like cr*p if I turn that off. |

Update your GFX card drivers! Your current driver is buggy, no doubt.

I updated them, but no difference (nVidia 9600 GT x 2).
I don't think it's a driver issue, I don't see how a video driver can mess with WM_PAINT, WM_SIZE messages and update / clipping regions. |

Drivers can definitely (indirectly) mess with WM_PAINT. I've had troubles with OpenGL-accelerated window surfaces that were erroneously drawn above other windows and stuff (similar to clipping issues). Try turning hardware acceleration off, and see if that helps. |

doesn't look like it's possible to turn it off with the nVidia control panel, and the troubleshooting button is disabled.
But we're talking about the splitter bar here, which is just a window. It's only 2D. |

also, it doesn't happen when certain controls are on the RHS of the splitter (such as report ctrl).

I had issues like this with vista with the task panel in my docking pane. I posted here (prettry sure I did) but never solved the problem. So I did this:
void TurnOffTheme( HWND hWnd ){ HINSTANCE hTheme; //load the DLLhTheme = LoadLibrary(TEXT( "uxtheme.dll")); if(hTheme){ HRESULT hr = S_OK; SETWINDOWTHEME pDllSetWindowTheme; pDllSetWindowTheme = (SETWINDOWTHEME)GetProcAddress(hTheme, "SetWindowTheme"); if(pDllSetWindowTheme){ (*pDllSetWindowTheme)(hWnd, L " ", L" ");} } } In my OnCreate code I do this: ...
if ( IsSystemVista() && m_TaskPanel.GetSafeHwnd() )
{ TurnOffTheme( m_TaskPanel.GetSafeHwnd() ); } ...This allows you to test if it is the theme and also allows you to still run with your theme elsewhere in your app since it only turns off the windows theme for a single window.
I have had to turn off themes in a number of places, especially when doing custom coloring (OnCtlColor) for certain controls in dialogs. I never figured out why I got the problem in the first place for the docking pane/task panel window we have but your descriptions of the problem are pretty much the same ones I have in our app.

tried another Win7 machine - different drivers / video hardware (but still NVidia), same problem.
Need to try with other hardware - Oleg, you got any NVidia hardware there? Tried 9600GT and 6200LE |

Hi,
Yes, I test it with NVIDIA GeForce 7600 GS but don't see it. What exactly you did with sample to catch it. Just run and see it ?
Do you test Windows 7 x64 in all cases ?

Any chance you can make a video of how you do this? I have Win7 - x64 and also don't see this. I ran the same code you all have from 13.2.1.
This machine has a NVIDIA Quadro PCI-E Series card. I leave Aero ON for the test. Do you see it running the exe from here? http://codejock.com/downloads/samples/dockingpane.asp |

I think I see how you make the sample simply by trying to make the sample look like the screen you posted, but still don't see any issue with it.

I'll try that app when I get to the office, ands see about a screen video capture (screen is 3 x 1920 x 1200 tho). All I did to repro is
a) compile the app (dynamically linked and unicode btw) b) run it c) drag any splitter bar d) take the screenshot e) mark-up the screenshot to show the problem The problem is it doesn't redraw the splitter bar once it is moved, what shows in the location of the splitter bar is what was in the panes under that location. |

the downloaded sample has the same problem
both 32 bit and 64 bit ones show the same problem. But it could be the video driver I guess. All tests that replicate this problem use the same NVidia driver distribution. But then probably quite a few people are using that driver. |

We see the same problem on Windows 7, 32 bit. Using NVIDIA GeForce Go 7900 GS display adapter, driver version 7.15.11.7948 dated 1/30/2009.
Very easy to duplicate using Codejock Pane Sample. Just move any splitter. Also observe same as Jimmy; move mouse over minimize/maximize/close button and problem goes away.

Hi,
Thanks, today catched it once with Windows 7 - checking what can be reason now.
Maybe one of solution is to disable trackers and use "live" resizing -
m_paneManager .UseSplitterTracker(FALSE); |
