[SOLVED] QCombobox size should fit in the largest string

smita30apr

Hi,

I have a QCombobox which contains strings of different length. And I want the length of the combobox should be resized with the largest string. I do it like this:

@Action_combo_box::Action_combo_box(QStringList char_list, const Scene *scene, QWidget *parent)
: QComboBox(parent)
, m_scene(scene)
{
qDebug()<<"Original width"<<width();
set_width(char_list);
addItems(char_list);
}

void Action_combo_box::set_width(const QStringList &char_list){
//find the lengthiest string
QString longest;
for (int i = 0; i < char_list.length(); i++) {
QString str = char_list.value(i);
if (str.length() > longest.length())
longest = str;
}

QFontMetrics font_metrics(fontMetrics());
int width = font_metrics.width(longest);
qDebug()<<"Longest str width"<<width;
setMinimumWidth(width);

}@

The above code does not work and my largest string is always clipped.

My output is:
Original width 100
Longest str width 49

which looks strange to me.
Any help??

Did you had a look at:
"setSizeAdjustPolicy":http://qt-project.org/doc/qt-5/qcombobox.html#sizeAdjustPolicy-prop

with
"QComboBox::AdjustToMinimumContentsLength":http://qt-project.org/doc/qt-5/qcombobox.html#SizeAdjustPolicy-enum

Yes I did. That did not help.

I solved the problem with

setMinimumWidth(minimumSizeHint().width());
