CComponentsForm provides page scroll if found more
than one pre defined page and is working with all derivated sub classes from CComponentsForm .
Pages are defined with setPageNumber(0...n) in items (1st page = 0). The item page number property is
defined in variable cc_page_number. The highest page number sets the
count of pages inside container to required value. Thats compellingly!
To show a page, we can use setCurrentPage(0...n ) and paintCurPage() or use directly paintPage(0...n).
Note: global paint() will show the current page. Default page is 0 (as first).
Use setCurrentPage(0...n) to change this before first call of paint().
Note: In CComponentsWindow class, these methods are applied to window body.
For examples, take a look into CTestMenu
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.
There was some problems with restore, hide, clean and save background of item parts,
seen in detailsline. kill() worked not really clean.
kill() works now as virtual member and uses paintBackgroundBoxRel().
In consequence of which:
-unnecessary members in subclasses removed.
-add some comments
It can be usefull to hold unchanged text to avoid unnecessary text
paintings. It's also also possible to force paint of text,
use forceTextPaint(). Use textChanged(), to evaluate current text changes.
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.
CProgressbar moved into components sub directory and adapt includes.
Progressbar objects are now usable as cc-item
TODO:
-some color and size corrections
-found some dub codes for sig and snr-bars, needs rework
