|
||
|
|
|
||
|
|
|
||
|
|
The TQGroupBox widget provides a group box frame with a title.
|
||
|
|
<p>
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
<p> A group box provides a frame, a title and a keyboard shortcut, and
|
||
|
|
displays various other widgets inside itself. The title is on top,
|
||
|
|
the keyboard shortcut moves <a href="focus.html#keyboard-focus">keyboard focus</a> to one of the group
|
||
|
|
box's child widgets, and the child widgets are usually laid out
|
||
|
|
horizontally (or vertically) inside the frame.
|
||
|
|
<p> The simplest way to use it is to create a group box with the
|
||
|
|
desired number of columns (or rows) and orientation, and then just
|
||
|
|
create widgets with the group box as parent.
|
||
|
|
<p> It is also possible to change the <a href="#orientation">orientation</a>() and number of
|
||
|
|
<a href="#columns">columns</a>() after construction, or to ignore all the automatic
|
||
|
|
layout support and manage the layout yourself. You can add 'empty'
|
||
|
|
spaces to the group box with <a href="#addSpace">addSpace</a>().
|
||
|
|
<p> TQGroupBox also lets you set the <a href="#title">title</a>() (normally set in the
|
||
|
|
constructor) and the title's <a href="#alignment">alignment</a>().
|
||
|
|
<p> You can change the spacing used by the group box with
|
||
|
|
<a href="#setInsideMargin">setInsideMargin</a>() and <a href="#setInsideSpacing">setInsideSpacing</a>(). To minimize space
|
||
|
|
consumption, you can remove the right, left and bottom edges of
|
||
|
|
the frame with <a href="#setFlat">setFlat</a>().

Changes the layout of the group box. This function is only useful
|
||
|
|
in combination with the default constructor that does not take any
|
||
|
|
layout information. This function will put all existing children
|
||
|
|
in the new layout. It is not good TQt programming style to call
|
||
|
|
this function after children have been inserted. Sets the number
|
||
|
|
of columns or rows to be <em>strips</em>, depending on <em>direction</em>.

|

|
|
<h3 class=fn>bool <a name="checkable-prop"></a>checkable</h3>
|
||
|
|
<p>This property holds whether the group box has a checkbox in its title.
|
||
|
|
<p>If this property is TRUE, the group box has a checkbox. If the
|
||
|
|
checkbox is checked (which is the default), the group box's
|
||
|
|
children are enabled.
|
||
|
|
<p> <a href="#setCheckable">setCheckable</a>() controls whether or not the group box has a
|
||
|
|
checkbox, and <a href="#isCheckable">isCheckable</a>() controls whether the checkbox is
|
||
|
|
checked or not.
|
||
|
|
|
||
|
|
<p>Set this property's value with <a href="#setCheckable">setCheckable</a>() and get this property's value with <a href="#isCheckable">isCheckable</a>().
|
||
|
|
<h3 class=fn>bool <a name="checked-prop"></a>checked</h3>
|
||
|
|
<p>This property holds whether the group box's checkbox is checked.
|
||
|
|
<p>If the group box has a check box (see <a href="#isCheckable">isCheckable</a>()), and the
|
||
|
|
check box is checked (see <a href="#isChecked">isChecked</a>()), the group box's children
|
||
|
|
are enabled. If the checkbox is unchecked the children are
|
||
|
|
disabled.
|
||
|
|
|
||
|
|
<p>Set this property's value with <a href="#setChecked">setChecked</a>() and get this property's value with <a href="#isChecked">isChecked</a>().
|
||
|
|
<h3 class=fn>int <a name="columns-prop"></a>columns</h3>
|
||
|
|
<p>This property holds the number of columns or rows (depending on <a href="#orientation-prop">TQGroupBox::orientation</a>) in the group box.
|
||
|
|
<p>Usually it is not a good idea to set this property because it is
|
||
|
|
slow (it does a complete layout). It is best to set the number
|
||
|
|
of columns directly in the constructor.
|
||
|
|
|
||
|
|
<p>Set this property's value with <a href="#setColumns">setColumns</a>() and get this property's value with <a href="#columns">columns</a>().
|
||
|
|
<h3 class=fn>bool <a name="flat-prop"></a>flat</h3>
|
||
|
|
<p>This property holds whether the group box is painted flat or has a frame.
|
||
|
|
<p>By default a group box has a surrounding frame, with the title
|
||
|
|
being placed on the upper frame line. In flat mode the right, left
|
||
|
|
and bottom frame lines are omitted, and only the thin line at the
|
||
|
|
top is drawn.
|
||
|
|
<p> <p>See also <a href="#title-prop">title</a>.
|
||
|
|
|
||
|
|
<p>Set this property's value with <a href="#setFlat">setFlat</a>() and get this property's value with <a href="#isFlat">isFlat</a>().

<h3 class=fn><a href="ntqt.html#Orientation-enum">Orientation</a> <a name="orientation-prop"></a>orientation</h3>
|
||
|
13 years ago
|
<p>This property holds the group box's orientation.
|
||
|
|
<p>A horizontal group box arranges it's children in columns, while a
|
||
|
|
vertical group box arranges them in rows.
|
||
|
|
<p> Usually it is not a good idea to set this property because it is
|
||
|
|
slow (it does a complete layout). It is better to set the
|
||
|
|
orientation directly in the constructor.
|
||
|
|
|
||
|
|
<p>Set this property's value with <a href="#setOrientation">setOrientation</a>() and get this property's value with <a href="#orientation">orientation</a>().

<h3 class=fn><a href="ntqstring.html">TQString</a> <a name="title-prop"></a>title</h3>
|
||
|
13 years ago
|
<p>This property holds the group box title text.
|
||
|
|
<p>The group box title text will have a focus-change keyboard
|
||
|
|
accelerator if the title contains &, followed by a letter.
|
||
|
|
<p> <pre>
|
||
|
|
g->setTitle( "&User information" );
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
This produces "<u>U</u>ser information"; Alt+U moves the <a href="focus.html#keyboard-focus">keyboard focus</a> to the group box.
|
||
|
|
<p> There is no default title text.
|
||
|
|
|
||
|
|
<p>Set this property's value with <a href="#setTitle">setTitle</a>() and get this property's value with <a href="#title">title</a>().
