finding similar functions of QTableWidget as that of QTableView

[Swati777999]

Hi All,

I am trying to draw a table inside a widget. See the code below

QWidget *myWidget = new QWidget();
QGridLayout *tableLayout = new QGridLayout();

QTableWidget *first_table=new QTableWidget();
tableLayout->addWidget(first_table,0,0);
first_table->setRowCount(7);
first_table->setColumnCount(2);
first_table->setColumnCount(2);
first_table->setColumnWidth(0,100);

QTableWidget *second_table=new QTableWidget();
tableLayout->addWidget(second_table,2,0);

QTableWidget *third_table=new QTableWidget();
tableLayout->addWidget(third_table,0,2);

QTableWidget *fourth_table=new QTableWidget();
tableLayout->addWidget(fourth_table,2,2);

myWidget->setLayout(tableLayout);
QMainWindow::setCentralWidget(myWidget);

I want to resize the outer widget at (0,0) to the size of the inner table. How is it possible to implement?

Thanks

I'm still not sure I quite understand. You have a layout (try not to call this a "table" as well, it's too confusing) containing 4 table widgets. As long as you show the other 3 table widgets I think it's going to be tricky to make the top-left one occupy the whole of the layout/outer table widget, as the other 3 and the cells they are in will take up some space.

Since you have first_table->setColumnWidth(0,100) did you try, say, first_table->setColumnWidth(1,0) and first_table->setRowHeight(1,0)? There are also setColumn/RowHidden() methods to consider?

As ever, trying out playing with settings in Qt Designer --- even if you're not going to use this in your final code --- may help.

Hi,

Do you mean you want to see only your top left QTableWidget ?

@SGaist

Whatever I've drawn for the table1 (top left one; first table) , I want to resize the inner table (QTableWidget first_table) according to the dimension of the outer table(QGridLayout tableLayout) i.e the inner table(QTableWidget first_table( shoudl coincide over the outer table(QGridLayout tableLayout).

Then I will use a loop to implement same logic for other tables in the above picture.

Hope I made my points more clearly.

With some experimentation, I got the desired result.
