|
|
|
|
|
|
The TQIconViewItem class provides a single item in a <a href="tqiconview.html">TQIconView</a>.
|
|
<p>
|
|
|
|
<p> A TQIconViewItem contains an icon, a string and optionally a sort
|
|
key, and can display itself in a TQIconView.
|
|
The class is designed to be very similar to <a href="ntqlistview.html">TQListView</a> and <a href="ntqlistbox.html">TQListBox</a>
|
|
in use, both via instantiation and subclassing.
|
|
<p> The simplest way to create a TQIconViewItem and insert it into a
|
|
TQIconView is to construct the item passing the constructor a
|
|
pointer to the icon view, a string and an icon:
|
|
<p> <pre>
|
|
(void) new TQIconViewItem(
|
|
iconView, // A pointer to a TQIconView
|
|
"This is the text of the item",
|
|
aPixmap );
|
|
</pre>
|
|
|
|
<p> By default the text of an icon view item may not be edited by the
|
|
user but calling <a href="#setRenameEnabled">setRenameEnabled</a>(TRUE) will allow the user to
|
|
perform in-place editing of the item's text.
|
|
<p> When the icon view is deleted all items in it are deleted
|
|
automatically.
|
|
<p> The <a href="tqiconview.html#firstItem">TQIconView::firstItem</a>() and <a href="#nextItem">TQIconViewItem::nextItem</a>() functions
|
|
provide a means of iterating over all the items in a TQIconView:
|
|
<p> <pre>
|
|
TQIconViewItem *item;
|
|
for ( item = iconView->firstItem(); item; item = item-><a href="#nextItem">nextItem</a>() )
|
|
do_something_with( item );
|
|
</pre>
|
|
|
|
<p> The item's icon view is available from <a href="#iconView">iconView</a>(), and its
|
|
position in the icon view from <a href="#index">index</a>().
|
|
<p> The item's selection status is available from <a href="#isSelected">isSelected</a>() and is
|
|
set and controlled by <a href="#setSelected">setSelected</a>() and <a href="#isSelectable">isSelectable</a>().
|
|
<p> The text and icon can be set with <a href="#setText">setText</a>() and <a href="#setPixmap">setPixmap</a>() and
|
|
retrieved with <a href="#text">text</a>() and <a href="#pixmap">pixmap</a>(). The item's sort key defaults
|
|
to text() but may be set with <a href="#setKey">setKey</a>() and retrieved with <a href="#key">key</a>().
|
|
The comparison function, <a href="#compare">compare</a>() uses key().
|
|
<p> Items may be repositioned with <a href="#move">move</a>() and <a href="#moveBy">moveBy</a>(). An item's
|
|
geometry is available from <a href="#rect">rect</a>(), <a href="#x">x</a>(), <a href="#y">y</a>(), <a href="#width">width</a>(), <a href="#height">height</a>(),
|
|
<a href="#size">size</a>(), <a href="#pos">pos</a>(), <a href="#textRect">textRect</a>() and <a href="#pixmapRect">pixmapRect</a>(). You can also test
|
|
against the position of a point with <a href="#contains">contains</a>() and <a href="#intersects">intersects</a>().
|
|
<p> To remove an item from an icon view, just delete the item. The
|
|
TQIconViewItem destructor removes it cleanly from its icon view.
|
|
<p> Because the icon view is designed to use drag-and-drop, the icon
|
|
view item also has functions for drag-and-drop which may be
|
|
reimplemented.
|
|

|
|
<b>Note:</b> Pixmaps with individual dimensions larger than 300 pixels may
|
|
not be displayed properly, depending on the <a href="tqiconview.html#Arrangement-enum">arrangement in use</a>. For example, pixmaps wider than 300 pixels
|
|
will not be arranged correctly if the icon view uses a
|
|
<a href="tqiconview.html#Arrangement-enum">TQIconView::TopToBottom</a> arrangement, and pixmaps taller than 300 pixels
|
|
will not be arranged correctly if the icon view uses a
|
|
<a href="tqiconview.html#Arrangement-enum">TQIconView::LeftToRight</a> arrangement.

</h3>
|
|
This virtual function is responsible for calculating the
|
|
rectangles returned by <a href="#rect">rect</a>(), <a href="#textRect">textRect</a>() and <a href="#pixmapRect">pixmapRect</a>().
|
|
setRect(), <a href="#setTextRect">setTextRect</a>() and <a href="#setPixmapRect">setPixmapRect</a>() are provided mainly
|
|
for reimplementations of this function.
|
|
<p> <em>text_</em> is an internal parameter which defaults to <a href="tqstring.html#TQString-null">TQString::null</a>.
|
|
|
|
<h3 class=fn>int <a name="compare"></a>TQIconViewItem::compare ( <a href="tqiconviewitem.html">TQIconViewItem</a> * i ) const<tt> [virtual]</tt>
|
|
</h3>
|
|
Compares this icon view item to <em>i</em>. Returns -1 if this item is
|
|
less than <em>i</em>, 0 if they are equal, and 1 if this icon view item
|
|
is greater than <em>i</em>.
|
|
<p> The default implementation compares the item keys (<a href="#key">key</a>()) using
|
|
<a href="tqstring.html#localeAwareCompare">TQString::localeAwareCompare</a>(). A reimplementation may use
|
|
different values and a different comparison function. Here is a
|
|
reimplementation that uses plain Unicode comparison:
|
|
<p> <pre>
|
|
int MyIconViewItem::compare( TQIconViewItem *i ) const
|
|
{
|
|
return key().compare( i-><a href="#key">key</a>() );
|
|
}
|
|
</pre>
|
|
|
|
<p> <p>See also <a href="#key">key</a>(), <a href="tqstring.html#localeAwareCompare">TQString::localeAwareCompare</a>(), and <a href="tqstring.html#compare">TQString::compare</a>().

|
|
|
<h3 class=fn>bool <a name="contains"></a>TQIconViewItem::contains ( const <a href="tqpoint.html">TQPoint</a> & pnt ) const
|
|
</h3>
|
|
Returns TRUE if the item contains the point <em>pnt</em> (in contents
|
|
coordinates); otherwise returns FALSE.
|
|
|
|
<h3 class=fn>bool <a name="dragEnabled"></a>TQIconViewItem::dragEnabled () const
|
|
</h3>
|
|
Returns TRUE if the user is allowed to drag the icon view item;
|
|
otherwise returns FALSE.
|
|
<p> <p>See also <a href="#setDragEnabled">setDragEnabled</a>().
|
|
|
|
<h3 class=fn>void <a name="dragEntered"></a>TQIconViewItem::dragEntered ()<tt> [virtual protected]</tt>
|
|
</h3>
|
|
This function is called when a drag enters the item's bounding
|
|
rectangle.
|
|
<p> The default implementation does nothing; subclasses may
|
|
reimplement this function.
|
|
|
|
<p>Example: <a href="fileiconview-example.html#x837">fileiconview/tqfileiconview.cpp</a>.
|
|
<h3 class=fn>void <a name="dragLeft"></a>TQIconViewItem::dragLeft ()<tt> [virtual protected]</tt>
|
|
</h3>
|
|
This function is called when a drag leaves the item's bounding
|
|
rectangle.
|
|
<p> The default implementation does nothing; subclasses may
|
|
reimplement this function.
|
|
|
|
<p>Example: <a href="fileiconview-example.html#x838">fileiconview/tqfileiconview.cpp</a>.
|
|
<h3 class=fn>bool <a name="dropEnabled"></a>TQIconViewItem::dropEnabled () const
|
|
</h3>
|
|
Returns TRUE if the user is allowed to drop something onto the
|
|
item; otherwise returns FALSE.
|
|
<p> <p>See also <a href="#setDropEnabled">setDropEnabled</a>().
|
|
|
|
<h3 class=fn>void <a name="dropped"></a>TQIconViewItem::dropped ( <a href="tqdropevent.html">TQDropEvent</a> * e, const <a href="tqvaluelist.html">TQValueList</a><TQIconDragItem> & lst )<tt> [virtual protected]</tt>
|
|
</h3>
|
|
|
|
<p> This function is called when something is dropped on the item. <em>e</em> provides all the information about the drop. If the drag object
|
|
of the drop was a <a href="tqicondrag.html">TQIconDrag</a>, <em>lst</em> contains the list of the
|
|
dropped items. You can get the data by calling

<p> To find the first item use <a href="tqiconview.html#firstItem">TQIconView::firstItem</a>().

Returns the icon of the icon view item if it is a picture, or 0 if

it is a picture. In the latter case use <a href="#picture">picture</a>() instead.
|
|
Normally you set the pixmap of the item with <a href="#setPixmap">setPixmap</a>(), but

you can subclass TQIconViewItem, reimplement this function and

Starts in-place renaming of an icon, if allowed.

<p> This function sets up the icon view so that the user can edit the

Returns 0.
|

<p> Make your derived classes return their own values for <a href="#rtti">rtti</a>(), so

that you can distinguish between icon view item types. You should

use values greater than 1000, preferably a large random number, to

|
Sets the bounding rectangle of the whole item to <em>r</em>. This

If <em>allow</em> is TRUE, the user can rename the icon view item by

|
|
Sets this item to be selectable if <em>enable</em> is TRUE (the default)

|
|
Selects or unselects the item, depending on <em>s</em>; it may also
|
|
unselect other items, depending on <a href="tqiconview.html#selectionMode">TQIconView::selectionMode</a>() and
|
|
<em>cb</em>.

<p> If <em>s</em> is FALSE, the item is unselected.

item is selected and the item previously selected is unselected.

<p> If <em>s</em> is TRUE and TQIconView::selectionMode() is <tt>Extended</tt>, the

item is selected. If <em>cb</em> is TRUE, the selection state of the
