|

| 73 |
|
|---|
| 74 |
|
|---|
| 75 | The QDockArea class manages and lays out QDockWindows.
|
|---|
| 76 | <p>
|
|---|
| 77 | <p> A QDockArea is a container which manages a list of
|
|---|
| 78 | <a href="qdockwindow.html">QDockWindow</a>s which it lays out within its area. In cooperation
|
|---|
| 79 | with the <a href="qdockwindow.html">QDockWindow</a>s it is responsible for the docking and
|
|---|
| 80 | undocking of <a href="qdockwindow.html">QDockWindow</a>s and moving them inside the dock
|
|---|
| 81 | area. QDockAreas also handle the wrapping of <a href="qdockwindow.html">QDockWindow</a>s to
|
|---|
| 82 | fill the available space as compactly as possible. QDockAreas can
|
|---|
| 83 | contain QToolBars since <a href="qtoolbar.html">QToolBar</a> is a <a href="qdockwindow.html">QDockWindow</a> subclass.
|
|---|
| 84 | <p> <a href="qmainwindow.html">QMainWindow</a> contains four QDockAreas which you can use for your
|
|---|
| 85 | QToolBars and QDockWindows, so in most situations you do not need
|
|---|
| 86 | to use the QDockArea class directly. Although QMainWindow contains
|
|---|
| 87 | support for its own dock areas it isn't convenient for adding new
|
|---|
| 88 | QDockAreas. If you need to create your own dock areas we suggest
|
|---|
| 89 | that you create a subclass of <a href="qwidget.html">QWidget</a> and add your QDockAreas to
|
|---|
| 90 | your subclass.
|
|---|
| 91 | <p> <center><img src="qmainwindow-qdockareas.png" alt="QMainWindow's QDockAreas"></center>
|
|---|
| 92 | <p> <a name="lines"></a>
|
|---|
| 93 | <em>Lines</em>. QDockArea uses the concept of lines. A line is a
|
|---|
| 94 | horizontal region which may contain dock windows side-by-side. A
|
|---|
| 95 | dock area may have room for more than one line. When dock windows
|
|---|
| 96 | are docked into a dock area they are usually added at the right
|
|---|
| 97 | hand side of the top-most line that has room (unless manually
|
|---|
| 98 | placed by the user). When users move dock windows they may leave
|
|---|
| 99 | empty lines or gaps in non-empty lines. Dock windows can be lined
|
|---|
| 100 | up to minimize wasted space using the <a href="#lineUp">lineUp</a>() function.
|
|---|
| 101 | <p> The QDockArea class maintains a position list of all its child
|
|---|
| 102 | dock windows. Dock windows are added to a dock area from position
|
|---|
| 103 | 0 onwards. Dock windows are laid out sequentially in position
|
|---|
| 104 | order from left to right, and in the case of multiple lines of
|
|---|
| 105 | dock windows, from top to bottom. If a dock window is floated it
|
|---|
| 106 | still retains its position since this is where the window will
|
|---|
| 107 | return if the user double clicks its caption. A dock window's
|
|---|
| 108 | position can be determined with <a href="#hasDockWindow">hasDockWindow</a>(). The position can
|
|---|
| 109 | be changed with <a href="#moveDockWindow">moveDockWindow</a>().
|
|---|
| 110 | <p> To dock or undock a dock window use <a href="qdockwindow.html#dock">QDockWindow::dock</a>() and
|
|---|
| 111 | <a href="qdockwindow.html#undock">QDockWindow::undock</a>() respectively. If you want to control which
|
|---|
| 112 | dock windows can dock in a dock area use <a href="#setAcceptDockWindow">setAcceptDockWindow</a>(). To
|
|---|
| 113 | see if a dock area contains a particular dock window use
|
|---|
| 114 | <a href="#hasDockWindow">hasDockWindow</a>(); to see how many dock windows a dock area
|
|---|
| 115 | contains use <a href="#count">count</a>().
|
|---|
| 116 | <p> The streaming operators can write the positions of the dock
|
|---|
| 117 | windows in the dock area to a <a href="qtextstream.html">QTextStream</a>. The positions can be
|
|---|
| 118 | read back later to restore the saved positions.
|
|---|
| 119 | <p> Save the positions to a QTextStream:
|
|---|
| 120 | <pre>
|
|---|
| 121 | ts << *myDockArea;
|
|---|
| 122 | </pre>
|
|---|
| 123 |
|
|---|
| 124 | <p> Restore the positions from a QTextStream:
|
|---|
| 125 | <pre>
|
|---|
| 126 | ts >> *myDockArea;
|
|---|
| 127 | </pre>

|
|---|
| 134 | <p> A dock window has two kinds of handles, the dock window handle
|
|---|
| 135 | used for dragging the dock window, and the splitter handle used to
|
|---|
| 136 | resize the dock window in relation to other dock windows using a
|
|---|
| 137 | splitter. (The splitter handle is only visible for docked
|
|---|
| 138 | windows.)
|
