screen coordinate problem in EasyCE

[LLcooL]

The problem you are talking about I have see when<br>I was developing the palettize code for EasyCE.<br><br>If the PPC was turned off with EasyCE running then on the logical palettize becomes off of context and EasyCE would display the image using the default palette. I got round this by calling<br>RealizePalette() each time the display is updated.

LLcooL, I don't think you guys are talking about the same thing. What you ought to do is just call RealizePalette when you app gets activation, instead of every frame.<br><br>sillycat, if you (or EasyCE) captures the mouse (SetCapture), then you need to release / recapture appropriately in the WM_ACTIVATE handler.<br><br>Dan East

Dan is corrrect. LLcool you've mistaken my question <br><br>thanks to both of you. i'll try that out later.<br>

Hm, I should have captured the mouse? Why?

[Dan East]

Well, since your app is fullscreen its not really necessary. I have to capture the mouse in DEXplor when the user drag / drops, because they can drag outside of my window.<br><br>It sounds like sillycat is not MoveWindow'ing his window to cover the whole screen when he gets WM_ACTIVATE. I also don't think he should be getting an activation message in the first place if a popup window he doesn't own is still covering his window.<br><br>DanEast

the taskbar() function is moving the windows to cover fullscreen.<br><br>and for the popup, it is not covering my window, my window covers it but yet my window seems not able to capture mouse events at that particular area where the popup is....<br><br>

I just took a look at the 1.5 source. In the "taskbar" function Jacco finds the system taskbar, gets its dimensions, gets the dimensions of your main window, then resizes the window's rect based on the taskbar size. I use a much simpler approach that should work for all cases. I simply explicitly size my main window to the size of the display. I also have not needed to manually hide the taskbar window. This is all I do when I gain activation:<br>[fixed]<br>SHFullScreen(hWnd, SHFS_HIDETASKBAR);<br>MoveWindow(hWnd, 0, 0, GetSystemMetrics(SM_CXSCREEN),<br>  GetSystemMetrics(SM_CYSCREEN), TRUE);[/fixed]<br><br>hWnd is of course the handle to your main window.<br><br>Dan East<br><br>[sub][color=blue]Last modification: Dan East - 12/18/01 at 20:27:51

Dan,<br><br>If I use your code to hide my taskbar, I get problems: When I click the first couple of lines, I get windows stuff flickering through my app... When I change back to my original lines, the problem is gone.<br><br>- Jacco.

Hmm. I use that in PQ, PWolf, and other software that takes over the display, and it works fine. I noticed in your WM_ACTIVATE handler you are not handling all cases of activation. There is one inactivate code (WA_INACTIVE), but multiple activation. So if LOWORD(wParam)!=WM_INACTIVE then your window is being activated.<br><br>Dan East
