Zooming QTableView

[Christian Ehrlicher]

Then you have to resize your header sizes accordingly.

@Christian-Ehrlicher

yes but I want to ask something.
Is there any other way to do zooming instead of changing fonts?

[Christian Ehrlicher]

No, not that I'm aware of.

[DzCode]

@Christian-Ehrlicher

I am asking this, because Icons and pixmaps in the decoration role does not change with the change of the font. image sizes also should change with zooming

Hi
You could maybe subclass HeaderView and overwrite paintSection
do your own image and text scaling.

Do you also need the actual cells to scale this way ?
You could add your own delegate and scale images and text too.

I am resizing the images inside a proxymodel now.

However, there is one thing left to solve my all problems.

I am using checkstaterole of my model to make some columns checkable. There is problem about resizing them. I dont want to replace them with QCheckBox. I created checboxes with the help of the Qt::ItemIsUserCheckable flag. How can I resize them?

hi
Ok that sounds good too.

I have never tried to style the "checkable" but I think you can control it with a delegate and
https://doc.qt.io/qt-5/qitemdelegate.html#drawCheck

Update: nope, it wont care if given bigger or smaller rect.
bascially it boils down to
style->drawPrimitive(QStyle::PE_IndicatorItemViewItemCheck, &opt, painter, widget);

@mrjj

I did it via stylesheet of QtableView::indicator.

Thanks both of you for your support

@DzCode
Good work. So even using stylesheets it zooms fast enough ?

[DzCode]

@mrjj I didnt test it with chrono since I didnt have a time to, but for user perspective, there is no problem if you have less table
