CComponentsForm: Overload member removeCCItem so we can use
cc_item as parameter.
CComponentsWindow: add member bool showFooter().
This allows to hide a footer in window.
It's not enough to insert an item object only. Also properties like
parent and index must be defined to inserted item to ensure that
positions are calculated correctly.
If cc-item is bound on a parent form, it's not enough
to replace the item object only, also properties like
parent and index must be moved to new item to ensure that positions are calculated correctly.
But it's matter for unbound cc-items.
The real position already used here, if item is bound to a parent.
(bound or embedded means: added with addCCItem() to a form)
This causes no separate calculation in paint methodes of embedded
sub items or sub forms and more nested sub forms.
CComponentsForm have also some new members
- exchangeCCItem() to exchange the order items
- setAppendOffset() to set an offset for auto append mode
Autoappend is enabled if x or y have value -1 (defined also in CC_APPEND)
x=horizontal, y=vertical
Is this activated, no separate calculation of incremental offset
is required.
However items with independent rendered parts, needs
a separate calculation. In some subclasses was this necessary.
Pointer is typically of type CComponentsForm or derived classes,
default intialized with NULL and serves to access for
properties of parent object by embedded items.
If items are used in forms it can be usefully to have a variable
which contains the real position on screen.
This can happen e.g. if an item contains separate render methods, because within forms
usual x/y values related to form dimensions and be converted.
Handling of minitv items are different to other item types
and need an explizit call of hide(). So it is possible to hide a form-
object without a extra call of hide() for minitv objects.
It's easier to work with smaller files.
Most files contain only one cc-class and their names are
derived on the particular class that is contained therein.
