\title Dynamic Layouts Example
|
|
\brief Shows how to re-orient widgets in running applications.
|
|
|
|
\e{Dynamic Layouts} implements dynamically placed widgets within running
|
|
applications. The widget placement depends on whether \c Horizontal or \c
|
|
Vertical is chosen.

|
\section1 Dialog Constructor
|
|
|
|
To begin with, the application creates the UI components by calling the
|
|
following methods:
|
|
|
|
\list
|
|
\li createRotatableGroupBox()
|
|
\li createOptionsGroupBox()
|
|
\li createButtonBox()
|
|
\endlist
|
|
|
|
It then adds the UI components to a GridLayout (\c mainLayout).
|
|
|
|
Finally, \c Dialog::rotateWidgets() is called.
|
|
|
|
\quotefromfile layouts/dynamiclayouts/dialog.cpp
|
|
\skipuntil createRotatableGroupBox
|
|
\printuntil setWindowTitle
|
|
|
|
\section1 Creating the Main Widgets
|
|
|
|
The \c createRotatableGroupBox() method creates a rotatable group box,
|
|
then adds a series of widgets:
|
|
|
|
\list
|
|
\li QSpinBox
|
|
\li QSlider
|
|
\li QDial
|
|
\li QProgressBar
|
|
\endlist
|
|
|
|
It goes on to add signals and slots to each widget, and assigns
|
|
a QGridLayout called \a rotatableLayout.
|
|
|
|
\skipto Dialog::createRotatableGroupBox
|
|
\printuntil /^\}/
|
|
|
|
\section1 Adding Options
|
|
|
|
\c createOptionsGroupBox() creates the following widgets:
|
|
\list
|
|
\li \c optionsGroupBox
|
|
\li \c buttonsOrientationLabel
|
|
\li \c buttonsOrientationComboBox. The orientation of the ComboBox is either
|
|
\c horizontal (default value) or \c vertical. These two values
|
|
are added during the startup of the application. It is not possible
|
|
to leave the option empty.
|
|
\endlist
|
|
|
|
\skipto Dialog::createOptionsGroupBox()
|
|
\printuntil /^\}/
|
|
|
|
\section1 Adding Buttons
|
|
|
|
createButtonBox() constructs a QDialogButtonBox called \c buttonBox
|
|
to which are added a \c closeButton, a \c helpButton and a
|
|
\c rotateWidgetsButton.
|
|
It then assigns a signal and a slot to each button in \c buttonBox.
|
|
|
|
\skipto Dialog::createButtonBox()
|
|
\printuntil /^\}/
|
|
|
|
|
|
\section1 Rotating the Widgets
|
|
|
|
Removes the current widgets and activates the next widget.
|
|
|
|
\quotefromfile layouts/dynamiclayouts/dialog.cpp
|
|
\skipto Dialog::rotateWidgets()
|
|
\printuntil rotatableLayout->addWidget(rotatableWidgets[i]
|
|
\printuntil }
|
|
\printuntil }
|
|
|
|
\include examples-run.qdocinc
