<p> If the TQBoxLayout's orientation is <ahref="ntqt.html#Orientation-enum">Horizontal</a> the boxes are
placed in a row, with suitable sizes. Each widget (or other box)
will get at least its minimum size and at most its maximum size.

In the example above we create a new TQToolBar in the constructor of a TQMainWindow subclass (so that the \fIthis\fR pointer points to the TQMainWindow). By default the toolbar will be added to the Top dock area, but we've moved it to the Left dock area.
.PP
A dock window is often used to contain a single widget. In these cases the widget can be set by calling setWidget(). If you're constructing a dock window that contains multiple widgets, e.g. a toolbar, arrange the widgets within a box layout inside the dock window. To do this use the boxLayout() function to get a pointer to the dock window's box layout, then add widgets to the layout using the box layout's QBoxLayout::addWidget() function. The dock window will dynamically set the orientation of the layout to be vertical or horizontal as necessary, although you can control this yourself with setOrientation().

Although a common use of dock windows is for toolbars, they can be used with any widgets. (See the TQt Designer and TQt Linguist applications, for example.) When using larger widgets it may make sense for the dock window to be resizable by calling setResizeEnabled(). Resizable dock windows are given splitter-like handles to allow the user to resize them within their dock area. When resizable dock windows are undocked they become top level windows and can be resized like any other top level windows, e.g. by dragging a corner or edge.

You should also implement minimumSize() to ensure your layout isn't resized to zero size if there is too little space.

A QLayoutIterator is not protected against changes in its layout. If the layout is modified or deleted the iterator will become invalid. It is not possible to test for validity. It is safe to delete an invalid layout; any other access may lead to an illegal memory reference and the abnormal termination of the program.

Layout - The restrictions on window layout are such that some aspects of layout that are style-dependent cannot be achieved using QLayout. Changes are being considered (and feedback would be appreciated) to make layouts TQStyle-able. Some of the restrictions involve horizontal and vertical widget alignment and widget size (covered below).

Widget size - Aqua allows widgets to have specific fixed sizes. TQt does not fully implement this behaviour so as to maintain multiplatform compatibility.

.PP
The default policy is Preferred/Preferred, which means that the widget can be freely resized, but prefers to be the size sizeHint() returns. Button-like widgets set the size policy to specify that they may stretch horizontally, but are fixed vertically. The same applies to lineedit controls (such as TQLineEdit, TQSpinBox or an editable TQComboBox) and other horizontally orientated widgets (such as TQProgressBar). TQToolButton's are normally square, so they allow growth in both directions. Widgets that support different directions (such as TQSlider, TQScrollBar or TQHeader) specify stretching in the respective direction only. Widgets that can provide scrollbars (usually subclasses of TQScrollView) tend to specify that they can use additional space, and that they can make do with less than sizeHint().
