Here is the code.

QList<SomeClass> ModeTableEntries ; for (int row = 0; row < ModeTableEntries .length(); row++) { ui->EntriesTableWidget->insertRow(row); ui->EntriesTableWidget->setRowHeight(row, 45); ModeValues value = ModeTableEntries [row]; QTableWidgetItem* currentItem = new QTableWidgetItem(value .ModeText); if(TestModeEnabled == true) currentItem->setCheckState(Qt::Checked); else currentItem->setCheckState(Qt::Unchecked); ui->EntriesTableWidget->setItem( row, 0, currentItem); currentItem->setFlags(currentItem->flags()^(Qt::ItemIsEditable )); }

The problem is that I cannot style the default implementation of the QTableWidgetItem(QCheckbox) that is part of the QTableWidgetItem.

@Christian-Ehrlicher Alright, thanks!

@mrjj That's it, thanks :)

Hi
Well it could work but you will have the issue that a row can only be one height so
if one big and the rest small, it will look odd.

But if all chart will be ca same size yes it should work ok.

Alternatively, you could tweak this
https://doc.qt.io/qt-5/qtwidgets-layouts-flowlayout-example.html
and put it into a QScrollArea.
Add this to it
https://wiki.qt.io/Widget-moveable-and-resizeable
Tweak it a bit and it should allow for a group of chars in various sizes and
scrollable.

As I already wrote on SO use selectionChanged() / itemSelectionChanged() signals ... when nothing is selected, you can't deselect items so how do you want to achieve a deselect here?

Okay proxy and listView is what solved the problem for me, thanks @SGaist and @Christian-Ehrlicher. I made a QListView and filtered it with the input of a QLineEdit and a sortFilterProxy, then I toke the data of the sortFilter and inserted it into a QTableView and cleaned the presentation with a delegate up. It works fast and snappy with my 20 exmaple data, I just hope that it keeps working as good with my ~300 data, but to get to this tests I have to finish other parts of my project first. I call this solved for now :-)

@SGaist Thank oyu, that worked!

Hi,

Can you explain what exactly you are trying to achieve ?

@A-A-SEZEN said in QTableWidget's width behaves strangely when applying any CSS:

Check QTableWidget font, before css and after.

Just changed the font to Consolas.
Anyways, adding

ui->tableWidget_memory->horizontalHeader()->resizeSections(QHeaderView::ResizeMode::ResizeToContents);

to my code solved this problem.

@hobbyProgrammer
After fetching data from database, https://doc.qt.io/qt-5/qvariant.html#isNull or (if you are SQL) https://doc.qt.io/qt-5/qsqlfield.html#isNull is the thing to test.

Thanks that worked

@y_belikov Well, follow the references until you reach the first cell (then you have circular references) or last cell without references.
For the first case you actually should see whether you visit one cell more than once.

@SGaist said in Add Qlabel as item in QTableview:

QStyledItemDelegate

Ok..I'll try with that.
from google search maybe this kind of output it will give, which maybe as our requirement.
0_1558578799369_da2ccc76-385d-40ee-954a-79cbbe227dc3-image.png

Else, I have some lengthy approach..implement custom label with mousepressevent handled which emits the object name and add these custom labels, 20 in HLayout and add hlayouts in a vlayout...

Thanks!

You won't get a paint event at all during drag'n'drop I would guess since the cursor is not directly painted by Qt when I'm correct.

Ok solved, Im gigantic NUB. I used itemAt instead of indexAt and took me a while to notice it... everything works! thanks!!!

Delegate widget has to be used.

Thanks I ended up doing the simplest thing:

QString descriptionText = QFontMetrics(table->font()).elidedText(m_description, Qt::ElideRight, uiSettings::descriptionTextWidth, 0); QTableWidgetItem *descriptionItem = new QTableWidgetItem(descriptionText); descriptionItem->setToolTip(m_description); table->setItem(r, 0, descriptionItem);

Forget my question. I have found the problem. It is not realted to QTableWidget. It just a problem with my QSS. In fact the scroll bar is present. But in "white on white"!
