[SOLVED]Window resize failed

[wilsonwing]

Hi, I am using 0.7.5 and still has the bug described in this post http://www.cegui.org.uk/phpBB2/viewtopic.php?f=5&t=4007&start=60#p20010.
Window resize failed.(Please see the video bellow)

On my PC, screen resolution 1024x768:
Program started at window size 800x600, no CEGUI problem, then press the maximize button on the top-right corner of the window.
The window size is now 1024x768, CEGUI still working good.
But when I press the button again, window size is now back to 800x600, the GUIs are distorted. (as descirbed by CABAListic)

Yes, I guess screenshots are in order. The following two screenshots show part of my menus in the initial screen resolution (800x600):

Then I resize the renderwindow to 1024x768, and this is what I get:

As you can see, the rendering area is not resized at all
...

On my Notebook, screen resolution 1280x800:
Program started at window size 800x600, no CEGUI problem, then press the maximize button on the top-right corner of the window.
The window size is now 1280x800, CEGUI layout is now out of the window, can only see parts of GUIs.
And resize back to 800x600, nothing shows up.
start up 800x600 :

My code :
ps. I have logged what iWidth and iHeight value are.
For window start up it is 796 and 596 (800-4, 600-4)
Maximize window it is 1024 and 768.
Back to 796 and 596 after resize again.

Code: Select all

void GUIManager::windowResized(unsigned int iWidth, unsigned int iHeight)
{
   CEGUI::Size size;
   size.d_width = static_cast<float>(iWidth);
   size.d_height = static_cast<float>(iHeight);
   CEGUI::System::getSingleton().notifyDisplaySizeChanged(size);
}

Please tell me if I don't explain it well, or any other info to help on this bug.

ps. This post is duplicate to http://www.cegui.org.uk/phpBB2/viewtopic.php?f=5&t=4007&start=75#p28095, but got no answer at the other post, so I post it here as a bug report.

Do the resize notifications appear in the CEGUI log? If so, I wonder what the people who get this issue are doing differently to those that do not get the issue

One thing to check is that you're notifying with the size of the Ogre rendering viewport and not the size of the host window (I think the size given by default is the size of the window). This being said, the effect of that particular error is usually a bit more subtle, but it's certainly worth checking.

If you let us know about the above two points, I'll raise it as an issue and try and check into it (currently I dread that it could be one of those "only happens on MS Windows" issues ).

Hello, CE.
Thanks for ypur reply first, and also thanks to your good CEGUI, I really like it.

Do the resize notifications appear in the CEGUI log?

Yes, as in the log, I resize the window from originally 792x566to 1024x708, than resize again back to 792x566.
(The window is 800x600 and 1024x768...I think the 792x566 and 1024x708 is the viewport size)

Code: Select all

21/01/2012 11:22:58 (Std)    Attempting to create Imageset 'ChineseFont_auto_glyph_images_ ' with texture only.

I don't understand very well on this question, but I will try to explain, please see the code:

Code: Select all

//I have a wndProc , notify when the window is resized.
LRESULT CALLBACK WindowProcedure::wndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)
{
...
case WM_SIZE:
   _windowSize(wParam, lParam);
...
}

//In _windowSize(wParam, lParam)
void WindowProcedure::_windowSize(WPARAM wParam, LPARAM lParam)
{
   int iWidth = LOWORD(lParam);
   int iHeight = HIWORD(lParam);

   //I logged the iWidth and iHeight here, it is 792 x 566 and 1024 x 708

   m_pOgreSystem->windowResized(iWidth, iHeight);
   m_pGUIManager->windowResized(iWidth, iHeight);
}


void OgreSystem::windowResized(unsigned int iWidth, unsigned int iHeight)
{
   const OIS::MouseState &ms = m_pMouse->getMouseState();
   ms.width = iWidth;
   ms.height = iHeight;
}

void GUIManager::windowResized(const UINT& iWidth, const UINT& iHeight)
{
   CEGUI::Size size;
   size.d_width = static_cast<float>(iWidth);
   size.d_height = static_cast<float>(iHeight);

   CEGUI::System::getSingleton().invalidateAllCachedRendering();
   CEGUI::System::getSingleton().notifyDisplaySizeChanged(size);
}


I don't do anything with the viewport.

ps.
Would you help me on my other post,
http://www.cegui.org.uk/phpBB2/viewtopic.php?f=10&t=5973&p=28297#p28297.
I am trying to render CEGUI window onto a Ogre Billboard, but no luck. Please give me a little help here, thank you

[CrazyEddie]

It appears that you are doing everything right, so I will need to dig into this a bit deeper and try and reproduce the issue. I don't suppose you'd be able to get a really minimal example together that reproduces this issue? (by minimal, I mainly mean something that just uses CEGUI with stock data files and Ogre).

I have made a mantis ticket here: http://www.cegui.org.uk/mantis/view.php?id=707 If you are able to come up with a minimal example, please attach the source to that there, and feel free to add any other diagnostic information too. I will try and look at it within the next week.

You've marked the topic as [SOLVED], and now I'm confused as to whether I'm supposed to be checking this out or not Please confirm one way or the other so I do not waste time hunting for issues that may not exist, thanks

Hi, CE.
It is not solved.
Just want to end this topic.
Sorry if I made it confusing.

[CrazyEddie]

Thanks for confirming This is just a note to say that I will be looking into this tomorrow - hopefully I can reproduce it.

CE.

[CrazyEddie]

I tested this by playing around with things in the CEGUI samples framework, but was not able to reproduce the issue - everything resized correctly whenever the size of the host window was changed.

From the code snippets you posted, I see you are using a custom window procedure, which is something the sample framework does not do when using the Ogre renderer. I'm willing to retest with that set up, but I need someone else to supply the code (as I do not, generally, do development on Windows). I'm willing to compile the test case myself, but I need some example source that clearly reproduces the issue.

Thanks,

CE.

hi, CE.
Sorry for the very late code. ( it has been more than a month )
I just have some time and make clean code to reproduce the bug.
And put it onto mantis .

Hope this helps. Thanks

[CrazyEddie]

Thanks for providing some test code for this issue. I will check it out soon.

I'd also like to state that this is an issue with my project, using 0.8.x's latest revisions.

Some added bit of information: the fonts appear to resize correctly for me; it's solely the windows which become distorted. There's no rush on my end for it to be fixed; however, I do appreciate that you will eventually look into the issue before the grand release.

[CrazyEddie]

Thanks.

I've not looked at it yet (real life getting in the way), but it will be looked at prior to the 1.0 (next) release. No ETA on that, other than to say the plan is still "this year"

[CrazyEddie]

To update on this.

@wilsonwing:
I have gotten around to examining the test case provided. I could reproduce an issue just fine, though on closer inspection it appears to be an usage error rather than a bug in CEGUI. While you are correctly injecting the notification to CEGUI, you're not informing Ogre that the window size has changed (which you must do when using a window that you created yourself). So, from the test case, in the function OgreSystem::windowResized adding the line:

Code: Select all

m_pWindow->windowMovedOrResized();

to notify Ogre seems to correct the issue.

I also noticed some other anomalies (these are not related to the issue reported, though I'm mentioning them since I noticed them), these appear to be related to your looknfeel needing some updates to be 100% compatible with 0.7.x. From a casual look, this mostly seems to be adding:

Code: Select all

<Property name="NonClient" value="True" />

for the __auto_titlebar__ and __auto_closebutton__ child definitions for the FrameWindow. You'll likely have to tweak positions of other layout content to compensate.

@ReGeX:
If your scenario is different to that of wilsonwing (meaning that you're using a different renderer, or if you are using ogre but you're not using a manually created host window) please open a ticket for your specific issue, providing as much information as possible about the configuration you're using, and provide a basic test case that reproduces the issue like wilsonwing did - because without these I am unable to reproduce these issues (which in turn means the issue is >95% likely not a CEGUI issue ).

Cheers,

CE.

Hi, CE.
I am sorry to provide a wrong bug report.
And find out to be my fault not using Ogre and CEGUI correctly.


Anyway, Thank you.

[CrazyEddie]

I am sorry to provide a wrong bug report.

Don't worry about it. While it can be a little frustrating for us, it's probably better to have a few false reports than get into a situation where people are afraid to report things and we end up missing a genuine bug

@ReGeX:
Following up again, since you said you were using a recent unstable version, I think yesterday I fixed the particular issue you were seeing.
