General and Desktop

Hi, thanks, will enter one - had to understand the problem first.

@abhishek999

You say you are using Qt 5.15.2 but your include path says Qt 5.15.0? Which one is correct?

And post code as text, don't post images please.

Ok,. To get smoother experience, have you tried running dumpcpp on that control?

That way you can get QAxObject subclasses specially suited for the control, and you don' have to write your own subclass like MyChildQaxWidget.

Nice !
Thanks for the feedback :-)

@Karsten-Heimrich said in Qt6Widgetsd.lib dooesn't exist:

qmake version found in D:\Qt\Tools\QtDesignStudio\qt6_design_studio_reduced_version\bin

This is wrong.
You need to select qmake from Qt version you installed. Did you install any Qt version?

@Pl45m4 Hi, I use below code to adjust widget size and the scroll bar is hide.Thank you very much.

QSize sizeTemp = viewport()->size(); testWidget->resize(sizeTemp);

For various reasons I've trashed WSL, so this is no longer an issue :) I've installed an Lubuntu 22.04 build VM

Thank you all for your help. Based on your analysis, here is my solution,
Create section

auto pTextItem=new QGraphicsTextItem("QGraphicsTextItem",pV); auto id=reinterpret_cast<void*>(dynamic_cast<QGraphicsItem*>(pTextItem));

deletion

void DeleteGraphics(void* id) { if (id==nullptr) return; auto scene=m_pQGraphicsView->scene(); auto items=scene->items(); QGraphicsItem* item = static_cast<QGraphicsItem*>(id); if(items.contains(item)){ scene->removeItem(item); delete item; } }

Hi,

That's because it's in a layout inside another widget.

On a side note, please format your code properly using coding tags or the </> button in the editing toolbar.

What did you do to fix the problem ?

Hi,

Which version of Qt ?
On which OS ?
Do you have the same issue if the other widget is not a QVideoWidget ?

Hi and welcome to devnet,

One thing that looks wrong is your if condition. 1080p is 1920x1080.

One thing you should try is the latest version of Qt 6. Improvements have happened on the High DPI side.

You might want to post this question to Qt advanced docking systems github

As a quick solution, you can fix that image using some optimisation utilities.
On the MacOS, I successfully solved this problem using the ImageOptim.
On other platforms, there is some similar tools such as the Trimage for Linux and the pinga for Windows, but I didn't test these.

As the responsible person for creating the Qt Desgin Studio packages my view comes from how it is built - not so much how it is used and yes documentation how it can be extend is missing, mostly because we had no requests in that direction until now.

What's wrong with QVariant()?
