TQIconView can display and manage a grid or other 2D layout of +labelled icons. Each labelled icon is a <a href="qiconviewitem.html">TQIconViewItem</a>. Items +(TQIconViewItems) can be added or deleted at any time; items can be +moved within the TQIconView. Single or multiple items can be +selected. Items can be renamed in-place. TQIconView also supports +<a href="#draganddrop">drag and drop</a>. +<p> Each item contains a label string, a pixmap or picture (the icon +itself) and optionally a sort key. The sort key is used for +sorting the items and defaults to the label string. The label +string can be displayed below or to the right of the icon (see <a href="#ItemTextPos-enum">ItemTextPos</a>). +<p> The simplest way to create a TQIconView is to create a TQIconView +object and create some TQIconViewItems with the TQIconView as their +parent, set the icon view's geometry and show it. +For example: +<pre> + TQIconView *iv = new TQIconView( this ); + <a href="qdir.html">TQDir</a> dir( path, "*.xpm" ); + for ( uint i = 0; i < dir.<a href="qdir.html#count">count</a>(); i++ ) { + (void) new <a href="qiconviewitem.html">TQIconViewItem</a>( iv, dir[i], TQPixmap( path + dir[i] ) ); + } + iv-><a href="qwidget.html#resize">resize</a>( 600, 400 ); + iv-><a href="qwidget.html#show">show</a>(); + </pre> + +<p> The <a href="qiconviewitem.html">TQIconViewItem</a> call passes a pointer to the TQIconView we wish to +populate, along with the label text and a <a href="qpixmap.html">TQPixmap</a>. +<p> When an item is inserted the TQIconView allocates a position for it. +Existing items are rearranged if <a href="#autoArrange">autoArrange</a>() is TRUE. The +default arrangement is <a href="#Arrangement-enum">LeftToRight</a> -- the TQIconView fills up +the <em>left-most</em> column from top to bottom, then moves one column +<em>right</em> and fills that from top to bottom and so on. The +arrangement can be modified with any of the following approaches: +<ul> +<li> Call <a href="#setArrangement">setArrangement</a>(), e.g. with <a href="#Arrangement-enum">TopToBottom</a> which will fill +the <em>top-most</em> row from left to right, then moves one row <em>down</em> +and fills that row from left to right and so on. +<li> Construct each TQIconViewItem using a constructor which allows +you to specify which item the new one is to follow. +<li> Call <a href="#setSorting">setSorting</a>() or <a href="#sort">sort</a>() to sort the items. +</ul> +<p> The spacing between items is set with <a href="#setSpacing">setSpacing</a>(). Items can be +laid out using a fixed grid using <a href="#setGridX">setGridX</a>() and <a href="#setGridY">setGridY</a>(); by +default the TQIconView calculates a grid dynamically. The position +of items' label text is set with <a href="#setItemTextPos">setItemTextPos</a>(). The text's +background can be set with <a href="#setItemTextBackground">setItemTextBackground</a>(). The maximum +width of an item and of its text are set with <a href="#setMaxItemWidth">setMaxItemWidth</a>() +and <a href="#setMaxItemTextLength">setMaxItemTextLength</a>(). The label text will be word-wrapped if +it is too long; this is controlled by <a href="#setWordWrapIconText">setWordWrapIconText</a>(). If +the label text is truncated, the user can still see the entire +text in a tool tip if they hover the mouse over the item. This is +controlled with <a href="#setShowToolTips">setShowToolTips</a>(). +<p> Items which are <a href="qiconviewitem.html#isSelectable">selectable</a> may be selected depending on the SelectionMode; +the default is <a href="#SelectionMode-enum">Single</a>. Because TQIconView offers multiple +selection it must display <a href="focus.html#keyboard-focus">keyboard focus</a> and selection state +separately. Therefore there are functions to set the selection +state of an item (<a href="#setSelected">setSelected</a>()) and to select which item displays +keyboard focus (<a href="#setCurrentItem">setCurrentItem</a>()). When multiple items may be +selected the icon view provides a rubberband, too. +<p> When in-place renaming is enabled (it is disabled by default), the +user may change the item's label. They do this by selecting the item +(single clicking it or navigating to it with the arrow keys), then +single clicking it (or pressing F2), and entering their text. If no +key has been set with <a href="qiconviewitem.html#setKey">TQIconViewItem::setKey</a>() the new text will also +serve as the key. (See <a href="qiconviewitem.html#setRenameEnabled">TQIconViewItem::setRenameEnabled</a>().) +<p> You can control whether users can move items themselves with +<a href="#setItemsMovable">setItemsMovable</a>(). +<p> Because the internal structure used to store the icon view items is +linear, no iterator class is needed to iterate over all the items. +Instead we iterate by getting the first item from the <em>icon view</em> +and then each subsequent (<a href="qiconviewitem.html#nextItem">TQIconViewItem::nextItem</a>()) from each +<em>item</em> in turn: +<pre> + for ( <a href="qiconviewitem.html">TQIconViewItem</a> *item = iv->firstItem(); item; item = item-><a href="qiconviewitem.html#nextItem">nextItem</a>() ) + do_something( item ); + </pre> + +TQIconView also provides <a href="#currentItem">currentItem</a>(). You can search for an item +using <a href="#findItem">findItem</a>() (searching by position or for label text) and +with <a href="#findFirstVisibleItem">findFirstVisibleItem</a>() and <a href="#findLastVisibleItem">findLastVisibleItem</a>(). The number +of items is returned by <a href="#count">count</a>(). An item can be removed from an +icon view using <a href="#takeItem">takeItem</a>(); to delete an item use <tt>delete</tt>. All +the items can be deleted with <a href="#clear">clear</a>(). +<p> The TQIconView emits a wide range of useful signals, including +<a href="#selectionChanged">selectionChanged</a>(), <a href="#currentChanged">currentChanged</a>(), <a href="#clicked">clicked</a>(), <a href="#moved">moved</a>() and +<a href="#itemRenamed">itemRenamed</a>(). +<p> <a name="draganddrop"></a> +<h3> Drag and Drop +</h3> +<a name="1"></a><p> TQIconView supports the drag and drop of items within the TQIconView +itself. It also supports the drag and drop of items out of or into +the TQIconView and drag and drop onto items themselves. The drag and +drop of items outside the TQIconView can be achieved in a simple way +with basic functionality, or in a more sophisticated way which +provides more power and control. +<p> The simple approach to dragging items out of the icon view is to +subclass TQIconView and reimplement <a href="#dragObject">TQIconView::dragObject</a>(). +<p> <pre> + TQDragObject *MyIconView::dragObject() + { + return new <a href="qtextdrag.html">TQTextDrag</a>( <a href="#currentItem">currentItem</a>()->text(), this ); + } + </pre> + +<p> In this example we create a <a href="qtextdrag.html">TQTextDrag</a> object, (derived from +<a href="qdragobject.html">TQDragObject</a>), containing the item's label and return it as the drag +object. We could just as easily have created a <a href="qimagedrag.html">TQImageDrag</a> from the +item's pixmap and returned that instead. +<p> TQIconViews and their TQIconViewItems can also be the targets of drag +and drops. To make the TQIconView itself able to accept drops connect +to the <a href="#dropped">dropped</a>() signal. When a drop occurs this signal will be +emitted with a TQDragEvent and a <a href="qvaluelist.html">TQValueList</a> of TQIconDragItems. To +make a <a href="qiconviewitem.html">TQIconViewItem</a> into a drop target subclass TQIconViewItem and +reimplement <a href="qiconviewitem.html#acceptDrop">TQIconViewItem::acceptDrop</a>() and +<a href="qiconviewitem.html#dropped">TQIconViewItem::dropped</a>(). +<p> <pre> + bool MyIconViewItem::acceptDrop( const <a href="qmimesource.html">TQMimeSource</a> *mime ) const + { + if ( mime-><a href="qmimesource.html#provides">provides</a>( "text/plain" ) ) + return TRUE; + return FALSE; + } + + void MyIconViewItem::dropped( <a href="qdropevent.html">TQDropEvent</a> *evt, const <a href="qvaluelist.html">TQValueList</a><TQIconDragItem>& ) + { + <a href="qstring.html">TQString</a> label; + if ( TQTextDrag::<a href="qtextdrag.html#decode">decode</a>( evt, label ) ) + setText( label ); + } + </pre> + +<p> See <a href="iconview-simple_dd-main-h.html">iconview/simple_dd/main.h</a> and <a href="iconview-simple_dd-main-cpp.html">iconview/simple_dd/main.cpp</a> for a simple drag and drop example +which demonstrates drag and drop between a TQIconView and a +<a href="qlistbox.html">TQListBox</a>. +<p> If you want to use extended drag-and-drop or have drag shapes drawn +you must take a more sophisticated approach. +<p> The first part is starting drags -- you should use a <a href="qicondrag.html">TQIconDrag</a> (or a +class derived from it) for the drag object. In <a href="#dragObject">dragObject</a>() create the +drag object, populate it with TQIconDragItems and return it. Normally +such a drag should offer each selected item's data. So in dragObject() +you should iterate over all the items, and create a <a href="qicondragitem.html">TQIconDragItem</a> for +each selected item, and append these items with <a href="qicondrag.html#append">TQIconDrag::append</a>() to +the TQIconDrag object. You can use <a href="qicondragitem.html#setData">TQIconDragItem::setData</a>() to set the +data of each item that should be dragged. If you want to offer the +data in additional mime-types, it's best to use a class derived from +TQIconDrag, which implements additional encoding and decoding +functions. +<p> When a drag enters the icon view, there is little to do.
