create checkboxes at run time
-
Hello, I have a QtableWidget and I when I receive a new data from Serial Port I create a new row in it with the data received. I want to create a new checkbox to QTableWidget's 4. column. The main purpose of checkboxes will be this: When pressed to a corresponding button, the row with the checkboxes checked will be transferred to another table. However, this method looks inefficient because then I need to create new checkboxes at run time as this: ( Because I do not know how many data I will receive from serial)
QCheckBox *checkbox = new QCheckBoxthis);Then how will I be able to check if these checkboxes are checked or not? Since they don't have a name?
So I am sure there are lots of better and easier methods for this purpose. What else I can use for that? Or how can I control the checkboxes created at runtime ? -

Before you need to go in this direction:QTableWidgetItems have a checkstate, you can enable viaQt::ItemIsUserCheckablein flags. If you use that you won't have to mess withQCheckBoxwidgets.@JonB Thanks. But I use CellDoubleClicked signals of the QTableWidget. So if a cell doubleclicked and user presses enter button, I send the data in the double clicked (selected) cell. So I believe I cannot use checkstate of the QTableWidgetItem. I believe they would interfere eachother.

I don't claim to know about that. I still would be reluctant to put a checkbox widget on when there's an in-built, but let's assume that is what you want.There are several ways you can do this, and still address
Then how will I be able to check if these checkboxes are checked or not? Since they don't have a name?
For simplicity, let's assume you add the
QCheckBoxonto the cells (setCellWidget()). Then you can access that checkbox via QWidget *QTableWidget::cellWidget(int row, int column) const.qobject_cast()the widget toQCheckBox *to see if it's a checkbox. Is that what you had in mind? -
