[Solved]Placing Widgets in the MainWindow



  • Hello Everyone,

    I am Qt-bigginer and am writting an application that consists of QMenuBar,QToolBar, MainWindow and QStatusBar.

    I am trying to set 2 Widgets in the center of main window.
    Right down the toolbar a QWidget that consists of lable, button and combobox and down to it, a table that the values have to be changed by clicking on the button at the QWidget.
    I have got a problem to place my widgets right down the QToolbar. In centralWidget, the lable,comboBox...will be shown in the middel of the window. Here is part of my code:

    @
    QWidget* centralWidget = new QWidget;
    QHBoxLayout* layout = new QHBoxLayout;
    QLabel* tool1 = new QLabel(tr("Tool1: "));
    QComboBox* combo_tool1 = new QComboBox();
    combo_tool1->addItem(tr("Select the tool"));
    combo_tool1->setEnabled(true);

    layout->addWidget(tool1);
    layout->addWidget(combo_tool1);
    centralWidget->setLayout(layout);
    
    setCentralWidget(centralWidget);
    

    @

    How am I supposed to fix it. :(

    Thank you



  • There are basically two options:

    • pass an "alignment":http://developer.qt.nokia.com/doc/qt-4.8/qt.html#AlignmentFlag-enum to QLayout::addWidget() or
      @
      layout->addWidget(tool1, 0, Qt::AlignTop);
      layout->addWidget(combo_tool1, 0, Qt::AlignTop);
      @
    • use another QVBoxLayout and a stretch to place it on top. This is particularly useful if you want to add other widgets below. In addition, a stretch can be used to glue the combo box to the label.
      @
      layout->addWidget(tool1);
      layout->addWidget(combo_tool1);
      layout->addStretch();

    QVBoxLayout* centralLayout = new QVBoxLayout;
    centralLayout->addLayout(layout);
    centralLayout->addStretch();

    centralWidget->setLayout(centralLayout);
    @
