I only use the GUI Designer plugin for Eclipse, did not modify anything, but
still the same, here is the very original full source code generated by the
designer - still the same.
This is what I did:
- create a new Qt project
File -> New -> Others -> Qt Jambi -> Qt Jambi Project (Using Designer Form)
- Drag and drop the Horizontal Layout to the main window, resize it to fill the
whole area
- Drag and drop the ScrollArea to the layout, change to 'always show scroll bar'
- Save and Run
public class Ui_Main implements com.trolltech.qt.QUiForm<QMainWindow>
{
public QWidget centralwidget;
public QWidget horizontalLayoutWidget;
public QHBoxLayout horizontalLayout;
public QScrollArea scrollArea;
public QWidget scrollAreaWidgetContents;
public QMenuBar menubar;
public QStatusBar statusbar;
public Ui_Main() { super(); }
public void setupUi(QMainWindow Main)
{
Main.setObjectName("Main");
Main.resize(new QSize(571, 222).expandedTo(Main.minimumSizeHint()));
QSizePolicy sizePolicy = new
QSizePolicy(com.trolltech.qt.gui.QSizePolicy.Policy.Expanding,
com.trolltech.qt.gui.QSizePolicy.Policy.Expanding);
sizePolicy.setHorizontalStretch((byte)0);
sizePolicy.setVerticalStretch((byte)0);
sizePolicy.setHeightForWidth(Main.sizePolicy().hasHeightForWidth());
Main.setSizePolicy(sizePolicy);
centralwidget = new QWidget(Main);
centralwidget.setObjectName("centralwidget");
horizontalLayoutWidget = new QWidget(centralwidget);
horizontalLayoutWidget.setObjectName("horizontalLayoutWidget");
horizontalLayoutWidget.setGeometry(new QRect(0, 20, 571, 161));
horizontalLayout = new QHBoxLayout(horizontalLayoutWidget);
horizontalLayout.setObjectName("horizontalLayout");
scrollArea = new QScrollArea(horizontalLayoutWidget);
scrollArea.setObjectName("scrollArea");
scrollArea.setWidgetResizable(true);
scrollAreaWidgetContents = new QWidget();
scrollAreaWidgetContents.setObjectName("scrollAreaWidgetContents");
scrollAreaWidgetContents.setGeometry(new QRect(0, 0, 567, 157));
scrollArea.setWidget(scrollAreaWidgetContents);
horizontalLayout.addWidget(scrollArea);
Main.setCentralWidget(centralwidget);
menubar = new QMenuBar(Main);
menubar.setObjectName("menubar");
menubar.setGeometry(new QRect(0, 0, 571, 21));
Main.setMenuBar(menubar);
statusbar = new QStatusBar(Main);
statusbar.setObjectName("statusbar");
Main.setStatusBar(statusbar);
retranslateUi(Main);
Main.connectSlotsByName();
} // setupUi
void retranslateUi(QMainWindow Main)
{
Main.setWindowTitle(com.trolltech.qt.core.QCoreApplication.translate("Main",
"MainWindow", null));
} // retranslateUi
}
thanks,
canal

Subject: Re: [Qt-jambi-interest] how to define widget resizable
First of all, Jambi uses Java naming convention, so ”Main ” should be ”main”...
You should try as simple example as possible, it looks like those size
constraints you have and I mentioned in first reply are causing your problems.
