Align QPushButton and QLineEdit
-
Hello,
QPushButton and QLineEdit have the same apparent height. But when I put both of them into a HBoxLayout it grows larger than any of the items. Upon closer inspection it seems that QPushButton has some kind of padding around it, please see the attached screenshot:

How to remove the padding so that the layout has minimum encompassing height (so that it touches QLineEdit)?

Sure:
@
#include "mainwindow.h"
#include <QtWidgets>MainWindow::MainWindow(QWidget *parent)
: QMainWindow(parent)
{
QWidget *widget = new QWidget(this);
QHBoxLayout *layout = new QHBoxLayout(this);
QLineEdit *line = new QLineEdit();
QPushButton *button = new QPushButton("Push Button");
widget->setLayout(layout);
widget->setFixedWidth(200);
layout->addWidget(line);
layout->addWidget(button);
layout->setContentsMargins(0, 0, 0, 0);
}MainWindow::~MainWindow()
{}
@
So my question is, why is the QLineEdit and QPushButton not touching the upper frame?
-
Try...
@
MainWindow::MainWindow(QWidget *parent)
: QMainWindow(parent)
{
QWidget *widget = new QWidget(this);
QHBoxLayout *layout = new QHBoxLayout(widget);
QLineEdit *line = new QLineEdit(widget);
QPushButton *button = new QPushButton("Push Button");
line->setFixedHeight(button->sizeHint().height());
widget->setFixedWidth(200);
layout->addWidget(line);
layout->addWidget(button);
layout->setContentsMargins(0, 0, 0, 0);
this->setCentralWidget(widget);
}

What I am doing is making the QLineEdit's height the same size of that of the QPushButton's.
Also since MainWindow already has a Layout associated with it, I have assigned widget as the parent of the lay out.
Hope that helps. -
Thanks but this seems to grow the QLineEdit height whereas I would like to shrink QPushButton height.
Perhaps the word "align" is a bit misleading. What I am after is how to remove the invisible padding around QPushButton so that it does not grow the layout beyond QLineEdit's height.

Thank you for the reply. Unfortunately the style sheet distorts the whole GUI (button gets square-shaped and the widgets misalign). But! It seems it is a Mac-only issue as the very first try from above works under Qt 4.8 on Ubuntu. I filed a bug report, thanks once more for the help!
