Hi,

Some of the recent changes to maximize/minimize handling and/or SerializePlacement() causes that theide is no longer started in maximized state. The problem is, that now it doesn't restore correctly the state after restart, i.e. if I close maximized ide, it opens in normal state next time.

The logs from serialization say (only ide serialization related logs shown here for clarity):
// Backup serialization before loading new data from file
TopWindow::SerializePlacement / write
minimized = false, maximized = true
rect = [0, 0] - [0, 0] : (0, 0), overlapped = [0, 0] - [0, 0] : (0, 0)

// LoadFromFile(ide); (ide/idewin.cpp:1003)
TopWindow::SerializePlacement / read
minimized = false, maximized = true
rect = [0, 15] - [1024, 600] : (1024, 585), overlapped = [0, 0] - [0, 0] : (0, 0)

// StoreToFile(ide); (ide/idewin.cpp:1031)
TopWindow::SerializePlacement / write
minimized = false, maximized = false
rect = [8, 32] - [1016, 592] : (1008, 560), overlapped = [0, 0] - [0, 0] : (0, 0)

// StoreToFile(ide); (ide/idewin.cpp:1036)
TopWindow::SerializePlacement / write
minimized = false, maximized = false
rect = [8, 32] - [1016, 592] : (1008, 560), overlapped = [0, 0] - [0, 0] : (0, 0)

As you can see, the StoreToFile() is called twice and between the calls the ide.state changes its value. I tried to track down where the change occures and got into ProcessEvents() call Then I got lost (couldn't find out which event triggers the change). The backtrace at this point was:

main (argc=1, argv=0xbffff984, envptr=0xbffff98c) at /home/h/upp-production/uppsrc/ide/idewin.cpp:731

I'm afraid that fixing this goes beyond my abilities Sad Mirek, (or any other volunteer Smile ), could you have a look at it? It is not really that much annoying to maximize theide every time, but my desire for perfection suffers Wink

BTW: In GUI_APP_MAIN there is (ide/idewin.cpp:839):
		Ide ide;
		ide.Maximize();
The call to Maximize is overwritten later, so it doesn't really matter and could be removed.

Best regards,
Honza

I do not see that...

Weird Confused Anyone else having this kind of trouble? If not, then it might be specific to my system (Arch Linux,GCC 4.5.2) in which case I would probably have to do all the work to figure it out...

SerializePlacement() itself works well, I tested it using uppdev/X11minmax. I only see this happen in theide. From where I stopped last time when debugging it looks like theide receives an event changing state, but that should only from user interaction (which I obviously didn't do). I will try to check the logs from ProcessEvents, maybe it'll tell something usefull.

I tracked it down. Theide receives WM_STATE event, which it properly digests and switches to overlapped mode. So the last question remains: Where the hell does that event come from?? I suspect my desktop environment, that is XFCE.

In my desktop (gnome, sometimes kde) upp also doesn't restore maximized state properly. Window is almost maximized - that means it occupies the whole screen with padding 5 pixels and still can be maximized. Strange Smile

Finally someone who sees the problem Smile The padding comes from TopwWindow::SerializePlacement():
		Rect limit = GetWorkArea();
		// ...
	#ifdef PLATFORM_X11
		Rect fm = windowFrameMargin; //<this returns empty Rect...
		if((fm.left|fm.right|fm.top|fm.bottom) == 0)
			fm = Rect(8, 32, 8, 8); // ... so this is chosen as safe values
		limit.left += fm.left;
		limit.right -= fm.right;
		limit.top += fm.top;
		limit.bottom -= fm.bottom;
#endif


But now I am even more puzzled, since you are using different desktop environments than me. So what else could cause that Mirek doesn't see the problem? The version of X? I am using pretty new one:

Ah sorry, this is misunderstanding. I was only commenting to

"As you can see, the StoreToFile() is called twice and between the calls the ide.state changes its value."

Because from the log:

// StoreToFile(ide); (ide/idewin.cpp:1031)
TopWindow::SerializePlacement / write
minimized = false, maximized = false
rect = [8, 32] - [1016, 592] : (1008, 560), overlapped = [0, 0] - [0, 0] : (0, 0)

// StoreToFile(ide); (ide/idewin.cpp:1036)
TopWindow::SerializePlacement / write
minimized = false, maximized = false
rect = [8, 32] - [1016, 592] : (1008, 560), overlapped = [0, 0] - [0, 0] : (0, 0)


I see no differences. I will have yet to test (and hopefully fix) this in Linux.

I'm also using the newest possible (but stable) version. Maximizing is not the only problem. The best show starts with compiz enabled. Resizing the window causes intensive flickering and restored maximized window is shifted down (I can't see part of the bottom window and I cant do anything about it (move or maximize)).
But the most irritating problem under gome no matter if compiz is enabled or not is debugging. If I click on the debugged window after a short while the parent window (theide) pops up. Can anyone confirm that?

Oups, my mistake Embarassed I actually meant to say that "the ide.state changes between the LoadFromFile() and first SaveToFile() call". Sorry for confusion Rolling Eyes

OK, looks like everything is nuked after I have applied minimize/maximize patches. Confirming both problems.

Well, it looks like X11 tries to reposition windows on its own on create, that is what is causing the mess.

I have tried to fix this by ignoring first set of ConfigureNotify (while waiting for FocusIn), then placing the new position to the window. Ugly hack for ugly system....

Please check!

Thanks Mirek,
I can confirm that it now works as expected. I just still wonder why the desktop environment sends such event... Thinking of it now, theide is not the only program that makes problem, evince (PDF viewer) usually starts shifted about half width to the left, off-screen. I suppose this is because xfce tries to position the windows to minimize overlaps (something like primitive tiling). It seems like not really well thought idea if it disrupts otherwise well written programs Confused

I guess it is not so bad in Ubuntu, it actually tries to move windows to quite inteligent positions. The problem, of course, is that sometimes you want this and sometimes you do not... Smile

But thankfully, now U++ can do both.

It's common behavior of *nix window managers, they *do* handle the placement of newly opened windows. Actually there are usually several options/strategies in desktop settings, how the window manager should place new windows on the desktop.

So it's not an defect, but effect. Smile

Strange. Function void TopWindow::SyncState0() (file TopWinX11.cpp, line 124) need to have opened window.
Because Maximize don't work until window realy not opened.

I use this code to work Maximize function:
void MainWindow::Setup(){
	if(splitter<1000 || splitter>9000) sp.SetPos(7700); else sp.SetPos(splitter);
	Open();
	Ctrl::ProcessEvents();
	LoadLocalSettings(); //Load settings from .cfg-file
	if (maximized) Maximize(); 
}

But in this case, filling of window content exposed to user.

Solution found! Please apply patch!

File TopWinX11.cpp
svn 3546

function
void TopWindow::Open(Ctrl *owner)
(line 235-338)

Near end of function I add Line

SyncState0();


result function will be:
void TopWindow::Open(Ctrl *owner)

	int version = 5;
	XChangeProperty(Xdisplay, GetWindow(), XAtom("XdndAware"), XA_ATOM, 32,
					0, (byte *)&version, 1);
	SyncState0();  // ############ This Added line! ###########
	FixIcons();
}


After this correction, function Maximize work perfectly.
And function SerializePlacement(s) fully work.

PS
I'm not shure about place of call SyncState0() may be we must place it a bit early.
