[SOLVED] Adding to a QGridLayout the way Creator can.

[mrjj]

Hi
In Creator you can add widgets to a QGridLayout
and it can add / remove Columns doing so.

So If have w1 w2 w3
I can drag between a widget w2 and w3 to get
w1 w2 MyNew w3

How can I do this from code / dynamic ? (seems not to be possible)
The

void QGridLayout::addWidget(QWidget * widget, int row, int column, Qt::Alignment alignment = 0)

Will replace what ever widget already in row, column, not make room for new one.

Thank you

Hi,

Just put the widget on the row/column you want:

QGridLayout *layout = new QGridLayout;
layout->addWidget(new QPushButton(tr("Test1")), 0, 0);
layout->addWidget(new QPushButton(tr("Test2")), 1, 1);
layout->addWidget(new QPushButton(tr("Test3")), 2, 2);

@SGaist
well I want to (later) insert a new one between Test1 and Test2. (imagine they are on same row)
Like I can in Creator.
Is that possible ?

It seems to replace any widget there.not add an extra.

Indeed, it seems that a replace + add combo is the only way

@SGaist
Hi, ok, i kinda fear that it would not work that way.
Im going to try to use a widget with a layout to fake a row instead.

[SGaist]

QHorizontalLayout + QVerticalLayout ?

You can also check the sources of designer to see how it's done there

@SGaist
I actually tried to use the source (luke) but I could simply not spot the files where such
drag and drop would happen. Grep didn't help me this time :(
