CComponentsHeader uses now CComponentsIconForm, which is now derived
from CComponentsFrmChain. Some methods should be now simplified and
allow to handle some modifications easier.
Use strictly CComponentsForm as parent parameter in constructors.
Some parts have been cleaned up (Constructors, init methodes removed)
New parameter makes it possible already add current item in constructor.
So in mostly situations is it not necessary to use explicit addCCItem(),
but addCCItem()is still valid and necessary in certain situations.
Affected are all cc-classes and their derivates.
Some classes must or can be adapted later. The function is
not currently restricted, because usage of parent parameter is not explicit
defined in constructors, see CImageInfo, here yet are used addCCItem()
methodes.
Generally this parameter is located in the constructors before bool has_shadow,
but it is not sure whether it would be better to use this parameter as the first.
That remains to be clarified.
So it's possible to use this method for all cc-items.
setCenterPos() comes now with parameter 'along_mode' (CC_ALONG_X, CC_ALONG_Y).
So it's possible to center in x or y direction. As default are
both directions predefined.
On some several cases it's possible that full resulution is not
visible on SD output or video-out modes like 576i/p.
So it's makes more sense to use current osd-settings for max size and
position.
This fixes also current behavior of Imageinfo.
Corners of header and footer were not adapted to parent form.
It's unsightly, if these elements are not using the same corner types
like the parent window.
Member initVarWindow() now used with parameters, so it's possible
to remove multiple code in constructors, but some class must be
renamed to CComponentsWindowMax.
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 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.
