Expanding lineEdit in QHBoxLayout is not working properly in qt plugins

[alizadeh91]

HI,
I've created a qt plugin with comboBox and lineEdit and put them in QHBoxLayout in Qt5. when i set sizepolicy of lineEdit to expanding, it doesn't works properly. actually it expands itself a little.

my code in plugin constructor in something like below:
Qt Code: Switch view
@comboBoxUnits = new QComboBox;
lineEditValue = new QLineEdit;

horizontalLayout = new QHBoxLayout(this);
horizontalLayout->setMargin(1);

comboBoxUnits->setSizePolicy(QSizePolicy::Preferred,QSizePolicy::Fixed);
lineEditValue->setSizePolicy(QSizePolicy::Expanding,QSizePolicy::Fixed);

horizontalLayout->addWidget(lineEditValue,0,Qt::AlignLeft);
horizontalLayout->addWidget(comboBoxUnits,0,Qt::AlignRight);

this->setLayout(horizontalLayout);@

what i am missing?

if you put

@comboBoxUnits->setSizePolicy(QSizePolicy::Fixed,QSizePolicy::Fixed);@

and set a Fixed width for comboBox does it still behave wrongly?

Yes!
