@keyterms:
wrapper object class,
@title:
wrapper class
@type:
class
@short:
Provides a wrapper class that hooks to an existing Qt graphic object modifying it.
@inherits:
[class]object[/class]
[class]widget[/class]
@description:
This is a class for advanced KVIrc scripting.[br]
It can wrap any existing KVIrc widget.[br]
This class allows some unbelievable changes to the whole graphic environment of the kvirc,[br]
in fact, could hook every widget, you can modify the property or you can be inserted other widget as child of this...[br]
in short you have absolute liberty. [br]
The power of this class is fantastic, because it allows the change at "run time" of almost all the elements of the Kvirc.[br]
But to use this class in optimal way and to exploit its power, you have to know the Qt.... so you won't have limits [br]
The KVIrc Qt widgets are arranged in trees (just as the objects).[br]
The difference is that there are more toplevel widgets (and so more than one tree).[br]
You can use [fnc]$objects.dump()[/fnc] to take a look at the KVIrc Qt objects tree.[br]
Here is a part of the tree:[br][br]
Ptr 14332520: top level object: kvirc_frame, class KviFrame, visible, rect = -4, -4, 1024, 708
Ptr 17296024: object: qt_top_dock, class QDockArea
Ptr 14882136: object: qt_custom_toolbar, class KviCustomToolBar
Ptr 18143368: object: qt_dockwidget_internal, class QDockWindowTitleBar
[br][br]
Every listed widget has a "name", a "class" and a set of properties.[br]
The first entry in this example is a KVIrc server window, class "KviFrame" and name "kvirc_frame":
it is a toplevel widget.[br]
The "qt_top_dock", "qt_custom_toolbar" and the "qt_dockwidget_internal" are
direct children of that widget.[br]
To indicate a specific widget we will use the "class::name" form.[br]
So to indicate the main KVIrc frame you will use "KviFrame::kvirc_main_frame".
Look at this example:[br]
%A=$new(wrapper,0,test,KviFrame::kvirc_frame,KviStatusBar::unnamed)[br]
%A->$setBackGroundColor(FFFFFF)[br]
For first thing we create an object type wrapper,then we flow the tree that there from the command /object.dump and we will have:[br]
. [br]
. [br]
Ptr 14196288: top level object: kvirc_frame, class KviFrame, visible, rect = -4, -4, 1024, 712 [br]
. [br]
Ptr 17197360: object: unnamed, class KviStatusBar [br]
. [br]
. [br]
in this way we can follow the order, father->child from the top-level widget(KviFrame::kvirc_frame)[br]
to reach the child that interests us (KviStatusBar::unnamed)[br]
Then, following the syntax we will have:
%A=$new(wrapper,0,test,KviFrame::kvirc_frame,KviStatusBar::unnamed)
Now %A. will be point to the wrapped object, therefore we could modify its property or to consider it as if it were an object created by us in scripting. [br]
Obviously, deleting the created object (for example %A) you don't will delete the object of Kvirc (in this case the statusbar). [br]
Another example could be this:[br]
%A=$new(wrapper,0,test,KviFrame::kvirc_frame,QToolButton::kvirc.identityoptions)[br]
%A->$setProperty(usesBigPixmap,0)[br]
In this fool example with the function $setProperty, we has setted the property usesBigPixmap to False, making to become the small icons of the ToolBar.[br]
[br]
The wrapping object search can optionally start with a window
identifier with the following syntax: WinId::<window_id>.
