+This library contains auxilliary stuff from Qt/Embedded 2.3.x which
+is very useful but has been left out from qconfig-qpe.h.
+
+Note: We can't just enable the said classes in our qconfig, because that
+ would mean we no longer could link to a sharp rom libqpe.
+
+Also note: We don't ship that embedded in libopie2
+ (nor do we use it from libopie2), because we want to keep
+ libopie2 LGPL - hence Opie stuff using these classes is also here.
+
+It could be useful to eventually have some original classes
+providing similar functionality.

+ \brief The QColorDialog class provides a dialog widget for specifying colors.
+ \ingroup dialogs
+
+ The color dialog's function is to allow users to choose colors -
+ for instance, you might use this in a drawing program to allow the
+ user to set the brush color.
+
+ This version of Qt only provides modal color dialogs. The static
+ getColor() function shows the dialog and allows the user to specify a color,
+ while getRgba() does the same but allows the user to specify a color with an
+ alpha channel (transparency) value.
+
+ The user can store customCount() different custom colors. The custom
+ colors are shared by all color dialogs, and remembered during the
+ execution of the program. Use setCustomColor() to set the
+ custom colors, and customColor() to get them.

+ \ingroup dialogs
+
+ The QInputDialog is a simple dialog which can be used if you
+ need a simple input from the user. This can be text, a number or
+ an item from a list. Also a label has to be set to tell the user
+ what he/she should input.
+
+ In this Qt version only the 4 static convenience functions
+ getText(), getInteger(), getDouble() and getItem() of QInputDialog
+ are available.
+
+ Use it like this:
+
+ \code
+ bool ok = FALSE;
+ QString text = QInputDialog::getText( tr( "Make an input" ), tr( "Please enter your name" ), QString::null, &ok, this );
+ if ( ok && !text.isEmpty() )
+ ;// user entered something and pressed ok
+ else
+ ;// user entered nothing or pressed cancel
+ \endcode
+
+ There are more static convenience methods!
+
+ \sa getText(), getInteger(), getDouble(), getItem()
+*/
+
+/*!
+ \enum QInputDialog::Type
+
+ This enum type specifies the type of the dialog
+ (which kind of input can be done):
+
+ <ul>
+ <li>\c LineEdit - A QLineEdit is used for taking the input, so a textual or
+ (e.g. using a QValidator) a numerical input can be done. Using lineEdit()
+ the QLineEdit can be accessed.
+ <li>\c SpinBox - A QSpinBox is used for taking the input, so a decimal
+ input can be done. Using spinBox() the QSpinBox can be accessed.
+ <li>\c ComboBox - A read-only QComboBox is used for taking the input,
+ so one item of a list can be chosen. Using comboBox() the QComboBox
+ can be accessed.
+ <li>\c EditableComboBox - An editable QComboBox is used for taking the input,
+ so either one item of a list can be chosen or a text can be entered. Using
+ editableComboBox() the QComboBox can be accessed.
+ </ul>

+ \class QSplitter qsplitter.h
+ \brief The QSplitter class implements a splitter widget.
+
+ \ingroup organizers
+
+ A splitter lets the user control the size of child widgets by
+ dragging the boundary between the children. Any number of widgets
+ may be controlled.
+
+ To show a QListBox, a QListView and a QMultiLineEdit side by side:
+
+ \code
+ QSplitter *split = new QSplitter( parent );
+ QListBox *lb = new QListBox( split );
+ QListView *lv = new QListView( split );
+ QMultiLineEdit *ed = new QMultiLineEdit( split );
+ \endcode
+
+ In QSplitter the boundary can be either horizontal or vertical. The
+ default is horizontal (the children are side by side) and you
+ can use setOrientation( QSplitter::Vertical ) to set it to vertical.
+
+ By default, all widgets can be as large or as small as the user
+ wishes, down to \link QWidget::minimumSizeHint() minimumSizeHint()\endlink.
+ You can naturally use setMinimumSize() and/or
+ setMaximumSize() on the children. Use setResizeMode() to specify that
+ a widget should keep its size when the splitter is resized.
+
+ QSplitter normally resizes the children only at the end of a
+ resize operation, but if you call setOpaqueResize( TRUE ), the
+ widgets are resized as often as possible.
+
+ The initial distribution of size between the widgets is determined
+ by the initial size of each widget. You can also use setSizes() to
+ set the sizes of all the widgets. The function sizes() returns the
+ sizes set by the user.
+
+ If you hide() a child, its space will be distributed among the other
+ children. When you show() it again, it will be reinstated.
