|
||
|
|
|
||
|
|
|
||
|
|
The TQWidgetStack class provides a stack of widgets of which
|
||
|
|
only the top widget is user-visible.
|
||
|
|
<p>
|
||
|
|
|
||
|
|
<p> The application programmer can move any widget to the top of the
|
||
|
|
stack at any time using <a href="#raiseWidget">raiseWidget</a>(), and add or remove widgets
|
||
|
|
using <a href="#addWidget">addWidget</a>() and <a href="#removeWidget">removeWidget</a>(). It is not sufficient to pass
|
||
|
|
the widget stack as parent to a widget which should be inserted into
|
||
|
|
the widgetstack.
|
||
|
|
<p> <a href="#visibleWidget">visibleWidget</a>() is the <em>get</em> equivalent of raiseWidget(); it
|
||
|
|
returns a pointer to the widget that is currently at the top of
|
||
|
|
the stack.
|
||
|
|
<p> TQWidgetStack also provides the ability to manipulate widgets
|
||
|
|
through application-specified integer IDs. You can also translate
|
||
|
|
from widget pointers to IDs using <a href="#id">id</a>() and from IDs to widget
|
||
|
|
pointers using <a href="#widget">widget</a>(). These numeric IDs are unique (per
|
||
|
|
TQWidgetStack, not globally), but TQWidgetStack does not attach any
|
||
|
|
additional meaning to them.
|
||
|
|
<p> The default widget stack is frameless, but you can use the usual
|
||
|
13 years ago
|
<a href="ntqframe.html">TQFrame</a> functions (such as <a href="ntqframe.html#setFrameStyle">setFrameStyle</a>()) to add a frame.
|
||
|
13 years ago
|
<p> TQWidgetStack provides a signal, <a href="#aboutToShow">aboutToShow</a>(), which is emitted
|
||
|
|
just before a managed widget is shown.

<p> This signal is emitted just before a managed widget is shown if

that managed widget has an ID != -1. The argument is the numeric

</h3>
|

|
|
Adds widget <em>w</em> to this stack of widgets, with ID <em>id</em>.
|
||
|
|
<p> If you pass an id >= 0 this ID is used. If you pass an <em>id</em> of
|
||
|
|
-1 (the default), the widgets will be numbered automatically. If
|
||
|
|
you pass -2 a unique negative integer will be generated. No widget
|
||
|
|
has an ID of -1. Returns the ID or -1 on failure (e.g. <em>w</em> is 0).
|
||
|
|
<p> If you pass an id that is already used, then a unique negative
|
||
|
|
integer will be generated to prevent two widgets having the same
|
||
|
|
id.
|
||
|
|
<p> If <em>w</em> already exists in the stack the widget will be removed first.
