|
||
|
|
|
||
|
|
|
||
|
|
<p> The TQBoxLayout class lines up child widgets horizontally or
|
||
|
|
vertically.
|
||
|
|
<p>
|
||
|
|
|
||
|
|
<p> TQBoxLayout takes the space it gets (from its parent layout or from
|
||
|
4 months ago
|
the <a href="tqlayout.html#mainWidget">mainWidget</a>()), divides it up into a row of boxes, and makes
|
||
|
13 years ago
|
each managed widget fill one box.
|
||
|
4 months ago
|
<p> <center><img src="tqhbox-m.png" alt="Horizontal box with five child widgets"></center>
|
||
|
13 years ago
|
<p> If the TQBoxLayout's orientation is <a href="ntqt.html#Orientation-enum">Horizontal</a> the boxes are
|
||
|
13 years ago
|
placed in a row, with suitable sizes. Each widget (or other box)
|
||
|
|
will get at least its minimum size and at most its maximum size.
|
||
|
|
Any excess space is shared according to the stretch factors (more
|
||
|
|
about that below).
|
||
|
4 months ago
|
<p> <center><img src="tqvbox-m.png" alt="Vertical box with five child widgets"></center>
|
||
|
13 years ago
|
<p> If the TQBoxLayout's orientation is <a href="ntqt.html#Orientation-enum">Vertical</a>, the boxes are
|
||
|
13 years ago
|
placed in a column, again with suitable sizes.
|
||
|
|
<p> The easiest way to create a TQBoxLayout is to use one of the
|
||
|
4 months ago
|
convenience classes, e.g. <a href="tqhboxlayout.html">TQHBoxLayout</a> (for <a href="ntqt.html#Orientation-enum">Horizontal</a> boxes) or
|
||
|
|
<a href="tqvboxlayout.html">TQVBoxLayout</a> (for <a href="ntqt.html#Orientation-enum">Vertical</a> boxes). You can also use the
|
||
|
13 years ago
|
TQBoxLayout constructor directly, specifying its direction as <a href="#Direction-enum">LeftToRight</a>, <a href="#Direction-enum">Down</a>, <a href="#Direction-enum">RightToLeft</a> or <a href="#Direction-enum">Up</a>.
|
||
|
|
<p> If the TQBoxLayout is not the top-level layout (i.e. it is not
|
||
|
|
managing all of the widget's area and children), you must add it
|
||
|
|
to its parent layout before you can do anything with it. The
|
||
|
|
normal way to add a layout is by calling
|
||
|
|
parentLayout->addLayout().
|
||
|
|
<p> Once you have done this, you can add boxes to the TQBoxLayout using
|
||
|
|
one of four functions:
|
||
|
|
<p> <ul>
|
||
|
|
<li> <a href="#addWidget">addWidget</a>() to add a widget to the TQBoxLayout and set the
|
||
|
|
widget's <a href="layout.html#stretch-factor">stretch factor</a>. (The stretch factor is along the row of
|
||
|
|
boxes.)
|
||
|
|
<p> <li> <a href="#addSpacing">addSpacing</a>() to create an empty box; this is one of the
|
||
|
|
functions you use to create nice and spacious dialogs. See below
|
||
|
|
for ways to set margins.
|
||
|
|
<p> <li> <a href="#addStretch">addStretch</a>() to create an empty, stretchable box.
|
||
|
4 months ago
|
<p> <li> <a href="#addLayout">addLayout</a>() to add a box containing another <a href="tqlayout.html">TQLayout</a> to the row
|
||
|
13 years ago
|
and set that layout's stretch factor.
|
||
|
|
</ul>
|
||
|
|
<p> Use <a href="#insertWidget">insertWidget</a>(), <a href="#insertSpacing">insertSpacing</a>(), <a href="#insertStretch">insertStretch</a>() or
|
||
|
|
<a href="#insertLayout">insertLayout</a>() to insert a box at a specified position in the
|
||
|
|
layout.
|
||
|
|
<p> TQBoxLayout also includes two margin widths:
|
||
|
|
<p> <ul>
|
||
|
4 months ago
|
<li> <a href="tqlayout.html#setMargin">setMargin</a>() sets the width of the outer border. This is the width
|
||
|
13 years ago
|
of the reserved space along each of the TQBoxLayout's four sides.
|
||
|
4 months ago
|
<li> <a href="tqlayout.html#setSpacing">setSpacing</a>() sets the width between neighboring boxes. (You
|
||
|
13 years ago
|
can use <a href="#addSpacing">addSpacing</a>() to get more space at a particular spot.)
|
||
|
|
</ul>
|
||
|
|
<p> The margin defaults to 0. The spacing defaults to the same as the
|
||
|
|
margin width for a top-level layout, or to the same as the parent
|
||
|
|
layout. Both are parameters to the constructor.
|
||
|
4 months ago
|
<p> To remove a widget from a layout, call <a href="tqlayout.html#remove">remove</a>(). Calling
|
||
|
7 months ago
|
<a href="tqwidget.html#hide">TQWidget::hide</a>() on a widget also effectively removes the widget
|
||
|
|
from the layout until <a href="tqwidget.html#show">TQWidget::show</a>() is called.
|
||
|
4 months ago
|
<p> You will almost always want to use <a href="tqvboxlayout.html">TQVBoxLayout</a> and <a href="tqhboxlayout.html">TQHBoxLayout</a>
|
||
|
13 years ago
|
rather than TQBoxLayout because of their convenient constructors.

|
</h3>
|
||
|
|
Adds <em>widget</em> to the end of this box layout, with a <a href="layout.html#stretch-factor">stretch factor</a> of <em>stretch</em> and alignment <em>alignment</em>.
|
||
|
|
<p> The stretch factor applies only in the <a href="#direction">direction</a> of the TQBoxLayout, and is relative to the other boxes and
|
||
|
|
widgets in this TQBoxLayout. Widgets and boxes with higher stretch
|
||
|
|
factors grow more.
|
||
|
|
<p> If the stretch factor is 0 and nothing else in the TQBoxLayout has
|

|
|
a stretch factor greater than zero, the space is distributed
|

|
|
according to the TQWidget:sizePolicy() of each widget that's
|

involved.
|
||
|
13 years ago
|
<p> Alignment is specified by <em>alignment</em> which is a bitwise OR of <a href="ntqt.html#AlignmentFlags-enum">TQt::AlignmentFlags</a> values. The default alignment is 0, which means
|
||
|
13 years ago
|
that the widget fills the entire cell.
