I hacked around the above error - but had to undo the hack a bit later in the build - seems running some commands is OK with that subprocess.py, others aren't - weird..

Anyhow, got a bit further, but now get:
Code: [Select]

I'm *hoping* this is because my node.exe is still v10; and the minimum required version is v12 ;)

Not tested...  but https://smedley.id.au/tmp/dooble-2023.01.18-os2-qt6-20230121.zip for *qt6*

Hi Paul,

Dooble-QT6 starts here. I can key in "www.os2world.com", the page is coming up, I can see that some "google" things are loaded in the lower left corner and then Dooble-QT6 disappears. No popup.log or other indication what has gone wrong.

Greetings from Potsdam,
Mike

Hi

I still can not render any page on Dooble Qt6 on my ArcaOS VM. Dooble for Qt5 works as expected.

Quote
Tried:
- Qt6 libs - https://www.dropbox.com/s/j8ybbujncktdf22/qt6-6.2.4-os2-20230108.zip?dl=0
- Qt6Webee - https://smedley.id.au/tmp/qt6webee-20230115.zip
- Dooble   -  https://smedley.id.au/tmp/dooble-2023.01.18-os2-qt6-20230121.zip
Procedure
- VIRTUALADDRESSLIMIT=2560 on Config.sys
- Deleted .doodle on Home
First:
 highmem -c qt6*dll
Then:
 set HOME=C:\home2
 set EXCEPTQ=ZZ
 set PATH=C:\qt6\bin;%PATH%
 set BEGINLIBPATH=c:\qt6\lib
 dooble --disable-gpu

Dooble loads (with the usual logo shfit and meny shift) and console shows:
Quote
[C:\HOME\DESKTOP\DOOBLE-2023.01.18-OS2-QT6-20230121]dooble --disable-gpu

QQuickWidget is only supported on OpenGL. Use QQuickWindow::setGraphicsApi() to

Try:

set QTWEBENGINE_CHROMIUM_FLAGS="ignore-certificate-errors -ignore-ssl-errors -log-level=1"
Before starting Dooble....

I find it hard to follow your pace of news, encourage.
This last version of Dooble, in this version the pages are loaded from the first window.
21/01/23  9:54      7.178.338      0 a---  dooble.exe
13/01/23  8:41    257.356.880     43 a---  Qt6WebEe.dll
, seems a bit more stable than the
8/01/23  5:59      3.886.850  6.001 a---  dooble.exe
13/01/23  8:41    257.356.880     43 a---  Qt6WebEe.dll
version. But they work very similar to me, almost the same. Maybe this (21/01/23) last slower, in the opening of the first 4 windows. Then equally speed.
I can open many websites known in OS2, without problems. More that 10.
The Os2world website always closes the browser, and others similar. When this occurs the page shows me the error this 2 times in one web site:
Code: [Select]
QQuickWidget is only supported on OpenGL. Use QQuickWindow::setGraphicsApi() to
override the default.
QQuickWidget is only supported on OpenGL. Use QQuickWindow::setGraphicsApi() to
override the default.
If this error only occurs once, do not close the dooble.exe

I am running with
set EXCEPTQ=ZZ     
dooble.exe  (without any more)
without:
REM set QTWEBENGINE_CHROMIUM_FLAGS="ignore-certificate-errors -ignore-ssl-errors -log-level=1"

Saludos

I am maintaining my profile /home/.doble, without problems.
But if I have observed that when closing the dooble, the dll qt6webee.dll is still open and requires unlock qt6webee.dll. Especially when copying attention to when you copied a new version on top of the previous one. Restarting the entire system also helps.

In your particular case I think you are under Memori.
Try to do this and tell me how it run:
Virtualaddrreslimit = 1536
Restart the system
Create a Disk RAM with 512MB HPFS, and PUT the swapper in that newly created unit, IN ROOT X:\ SWAPPERXXX.
Restart Again
Now virtualaddresslimit = 3072
Restart and test dooble.
I understand that you have 4GB installed.

And ONLY if you want to experiment
Memlimit.exe to 4095

It is possible that the wpshell made strange things, if you do it, you close it instantaneous and restart, here all good.
saludos

Hi.

Sorry for the "almost" off topic. KO Myung-Hun posted on the Qt5 port Github that he needs Qt5Quick, Qt5QuickWidgets and Qt5QuickControls2 for the VLC ports. I don't know what are those for, but maybe it will be good to evaluate if they can fit on the Qt6 port on the future, because of the importance of VLC.

Hi Paul, latest seems to work much the same as previous. Needed to import the blocklist (new profile) to load os2world.

Hey Martin,

FWIW I see this on one of my VM's - when I get a moment,I'll try work out wtf is going on.

Cheers,

Paul

From \qt6\lib:
Qt6QuickControls2_dll.a
Qt6QuickWidgets_dll.a
Qt6Quick_dll.a

These are already present in the Qt6 port.

Cheers,

I'd expect that - I only rebuilt as there were a couple of changes requested in the dooble githib by OS/2 users :)

Hey all,

I'm *hoping* this is because my node.exe is still v10; and the minimum required version is v12 ;)

The good news:
Code: [Select]
{0}[c:\usr\local\bin] node --version
v12.22.12

The bad news:
The rollup error is still the same

Window geometry is definitely screwed up in Qt6....

Given the example rasterwindow - https://github.com/psmedley/qt6-base-os2/tree/main/examples/gui/rasterwindow

At https://github.com/psmedley/qt6-base-os2/blob/main/examples/gui/rasterwindow/rasterwindow.cpp#L58 it opens a window at coordinate 100,100 - which should be of size 300x200

I added a call:
Code: [Select]
    qInfo() << "Width: " << width() << "Height: " << height(); at https://github.com/psmedley/qt6-base-os2/blob/main/examples/gui/rasterwindow/rasterwindow.cpp#L113 to tell me the current height and width of the window.

On first run, it tells me:
Code: [Select]
Width:  240 Height:  160
Pretty sure the problem is somewhere in https://github.com/psmedley/qt6-base-os2/blob/main/src/plugins/platforms/os2/qos2window.cpp but it's not immediately clear what needs to change between Qt5 and Qt6....

Edit: interesting - qos2window knows the correct resolution, qt doesn't... Example after enabling loggin:
Code: [Select]
qt.qpa.events: QOS2Window(0x20046880,80000181,80000195,QRect(100,100 696x488),RasterWindow(0x12ff20)) QRect(0,0 696x488) isExposed() true window()->isVisible() true
qt.qpa.backingstore: QRegion(0,0 696x488) hasAlpha false
Width:  557 Height:  390

so Qt consistently thinks the window is  20% smaller than it actually is....

Commit to follow, but a new qos2.dll seems to address the menu issues - https://smedley.id.au/tmp/qt6-6.2.4-qos2-20230122.zip - drop this DLL into \qt6\lib\plugins\platforms

Short story - QScreen on OS/2 reported it was 120dpi; Qt defaults to 96 dpi - so Qt was applying a 'scaling' factor of 120/96 = 1.25 to some things....
