KContainerLayout is a class that will manage layout of it's child widgets. Here is an example of using this class:
KContainerLayout (QWidget * parent=0, const char * name=0, int orientation = KContainerLayout::Horizontal, bool homogeneos = FALSE, int spacing = 5, WFlags f=0, bool allowLines=TRUE) |
Constructs a KContainerLayout as child of parent
Parameters:
parent | The parent widget of the KContainerLayout |
name | The name of the widget |
orientation | The orientation of the container, either KContainerLayout::Horizontal or KContainer::Vertical |
homogeneous | If the container should split available size by all KContainerLayoutItem in equal parts |
spacing | The space to add between each widget and between the first/last and the borders |
f | Flags @see QFrame#QFrame |
allowLines | Flags @see QFrame#QFrame |
~KContainerLayout () |
The destructor
int getNumberOfWidgets () |
Returns the number of widgets inside this container
int packStart (QWidget *w, bool e=FALSE, bool f=FALSE,int p=1) |
Pack one widget to the start of the container after the previously packed on start widgets
Parameters:
w | The widget to be packed |
e | If the widget should use the whole size allocated to it |
f | If the widget should be sized to fill the whole space allocated to it (only makes sense with Expand=TRUE) |
p | Padding that should be used as the borders in each side of the widget |
int packEnd (QWidget *w, bool e=FALSE, bool f=FALSE,int p=1) |
Pack one widget to the end of the container after the previously packed on end widgets
Parameters:
w | The widget to be packed |
e | If the widget should use the whole size allocated to it |
f | If the widget should be sized to fill the whole space allocated to it (only makes sense with Expand=TRUE) |
p | Padding that should be used as the borders in each side of the widget |
void setOrientation (int i) |
Sets the orientation of the container, one of KContainerLayout::Horizontal or KContainer::Vertical
void setHomogeneos (bool b) |
Sets the container to use the same size to each widget he contains (TRUE) or not (FALSE) When homogeneous is true all widgets will be packed as if they had the Expand set to TRUE @see KContainerLayout#packStart @see KContainer#packEnd
void setStartOffset (int i) |
Sets the starting offset for this container @see _startOffset
void setEndOffset (int i) |
Sets the ending offset for this container @see _endOffset
const int orientation () |
Returns the current orientation of the container @see KContainerLayout#setOrientation
const bool homogeneos () |
Returns the current homogeneous state of the container @see KContainerLayout#setHomogeneous
const int spacing () |
Returns the current spacing of the container @see KContainerLayout#setSpacing
const int startOffset () |
Returns the starting offset for this container @see _startOffset
const int endOffset () |
Returns the ending offset for this container @see _endOffset
void sizeToFit () |
Resizes the container to be as small as necessary to display all widgets
void recalcLayout () |
Calculates the size necessary to display all widgets
QSize widgetSize (KContainerLayoutItem *item) |
Returns the size necessary for the widget represented by this KContainerLayoutItem
void repositionWidgets () |
Reposition all widgets on the container.
int numberOfWidgetsWithExpand () |
Returns the number of widgets that share the extra space on the container.
void calculateSizeHint () |
Calculate our size hint based on the sizeHint() of all out widgets, on our properties - expand and homogeneous, and on the KContainerLayoutItem properties.

QSize sizeOfLargerWidget () |
Return the size necessary by the largest widget on the container.
QSize idealSizeOfWidget (KContainerLayoutItem *item) |
Returns the ideal size for the widget represented by this KContainerLayoutItem.
const bool horizontal () |
Return TRUE if this is an horizontal container.
void resizeEvent (QResizeEvent *ev) |
Resizes the widget and repositions all widgets.
Reimplemented from QFrame
bool eventFilter (QObject *, QEvent *ev) |
Used to filter resize events from our parent if it isn't a KContainerLayout.
Reimplemented from QObject
QSize sizeHint () |
Returns our size hint. The size necessary to display this container.
Reimplemented from QWidget
int _orientation |
Keeps the orientation of the container one of KContainerLayout::Horizontal or KContainer::Vertical
bool _homogeneos |
Should we split our size in equal parts by all the widgets?
int _spacing |
Space to be used between widgets and between the first/last widget and the container borders.
int _startOffset |
Space between the starting border and the first widget
int _endOffset |
Space between the last widget and ending border
QList<KContainerLayoutItem> _startWidgets |
The list of all widgets packed on the start
QList<KContainerLayoutItem> _endWidgets |
The list of all widgets packed at the end
int _sizeForEach |
width or height we have for each widget
QSize _sizeHint |
our sizeHint that we will return on our implementation of sizeHint()
