Making a Qt custom widget without Qt Creator

Just final question.
It is easy to use custom plugins without all the plugin code using
promotion.No, I need real widget(plugin).
Well, I thought of it again, I think I'd better compile Qt Creator with mingw.
How can I do this?
According to this...it's a nightmare!!
Will I have to re-compile if I create a new plugin sometime later?
Or it's done once and forever?@Panoss
Its sort of a do once and use mingw Creator for ever with that version of Qt
But in a few version of Qt you might need to recompile Creator.Its not a nightmare as such ( webkit is: ) but it does take some (long) time.
If you plan on others to use your plugin , the VS way is still better :)
You will still use Creator etc and its just other compiler.And no, the whole reason to compile Creator with mingww is so it will load plugins compiled with
mingw. So as long as you do not upgrade mingw , then no need to ever recompile Creator for a new plugin.The normal Creator is compiled with Vs and only like VS compiled plugins.
So in my opinion, for your use case Visual Studio is better as its how it normally works and
all other installations of Qt can just use it. -
@Panoss
Super. Its fun with plugins.
We need more , one can never have too many Designer widgets :)Final note:
The debugger is a separate download.

This is often a surprise :)
-
You will need debugger :)
We all do.
And no its was not good surprise.
They come here and say.
"Program crash"
and we go like "ok, place a breakpoint and single step the function to find crash point."But it can wait till later i guess :)

Fast question:
This plugin will run on windows xp?
The app is for Xp?Note that from 5.7 ( think) its not tested on xp.
Might work or might not. Its not supported. -
@Panoss
Ok. just asking as XP is not on ppl mind anymore.
https://forum.qt.io/topic/73292/the-last-qt-version-that-supported-windows-xpSounds like using 5.6 is the best bet :)
Did u try that version of Creator on xp?
It didn't start or ?
Note that Xp in virtual machine do not have openGL (often) and can only work if started with some option

On XP I haven't tried Qt Creator yet.
I was thinking of trying an older version, and adjusting the code where necessary. -
Start a "Qt Custom Designer Plugin" project and it will be all prepared for that. This one is under "Other project" in the "New File or Project" dialog.
-
I make a New Project->Qt Custom Designer Widget, Name: I enter 'AnalogClock'->Next but I see no VS kit:
And no VS kit is auto detected.
Maybe I should add manually a VS kit?Should I make two projects? The 'main' project in wich the widget will be used, and the project of the widget (plugin)?

Ok, after adding msvc2015 32-bit in Maintenance tool, everything seems ok.
I built the poject, and a dll was created(!!wow) in my project 's debug folder.I also now have two folders:
c:\qt\5.8\mingw53_32\bin and
c:\qt\5.8\msvc2015\bin
which have a designer.exe inside.
I run them both (I suppose the one that should show my plugin is the msvc2015\bind\designer.exe) but in none of them appears my plugin.
Also the dll of my plugin was not copied in any of the folders of c:\qt\5.8. -

I copied it in C:\Qt\5.8\msvc2015\plugins\designer, but it failed: 'uses incompatible Qt library. Cannot mix debug and release libraries':
-
In the Qt Creator 's 'Release' button, I chose 'release', and build.
In folder C:\Documents\QtProjects\AnalogClockB\build-AnalogClockB-Desktop_Qt_5_8_0_MSVC2015_32bit-Release\release
a dll was created!!! I copied it in C:\Qt\5.8\msvc2015\plugins\designer....and...it appeared in Qt Designer!!! Wow!!Thank you all guys, your help was great!
