|
|---|
| 57 |
|
|---|
| 58 |
|
|---|
| 59 | The QToolBar class provides a movable panel containing
|
|---|
| 60 | widgets such as tool buttons.
|
|---|
| 61 | <p>
|
|---|
| 62 |
|
|---|
| 63 | <p> A toolbar is a panel that contains a set of controls, usually
|
|---|
| 64 | represented by small icons. It's purpose is to provide quick
|
|---|
| 65 | access to frequently used commands or options. Within a
|
|---|
| 66 | <a href="qmainwindow.html">QMainWindow</a> the user can drag toolbars within and between the
|
|---|
| 67 | <a href="qdockarea.html">dock areas</a>. Toolbars can also be dragged
|
|---|
| 68 | out of any dock area to float freely as top-level windows.
|
|---|
| 69 | <p> QToolBar is a specialization of <a href="qdockwindow.html">QDockWindow</a>, and so provides all
|
|---|
| 70 | the functionality of a QDockWindow.
|
|---|
| 71 | <p> To use QToolBar you simply create a QToolBar as a child of a
|
|---|
| 72 | QMainWindow, create a number of <a href="qtoolbutton.html">QToolButton</a> widgets (or other
|
|---|
| 73 | widgets) in left to right (or top to bottom) order and call
|
|---|
| 74 | <a href="#addSeparator">addSeparator</a>() when you want a separator. When a toolbar is
|
|---|
| 75 | floated the caption used is the label given in the constructor
|
|---|
| 76 | call. This can be changed with <a href="#setLabel">setLabel</a>().
|
|---|
| 77 | <p>
|
|---|
| 78 |
|
|---|
| 79 | <pre> QToolBar * fileTools = new QToolBar( this, "file operations" );
|
|---|
| 80 | fileTools-><a href="#setLabel">setLabel</a>( "File Operations" );
|
|---|
| 81 | fileOpenAction-><a href="qaction.html#addTo">addTo</a>( fileTools );
|
|---|
| 82 | fileSaveAction-><a href="qaction.html#addTo">addTo</a>( fileTools );
|
|---|
| 83 | </pre>
|
|---|
| 84 | <p> This extract from the <a href="simple-application-example.html">application/application.cpp</a> example shows
|
|---|
| 85 | the creation of a new toolbar as a child of a <a href="qmainwindow.html">QMainWindow</a> and
|
|---|
| 86 | adding two QActions.
|
|---|
| 87 | <p> You may use most widgets within a toolbar, with QToolButton and
|
|---|
| 88 | <a href="qcombobox.html">QComboBox</a> being the most common.
|
|---|
| 89 | <p> If you create a new widget on an already visible QToolBar, this
|
|---|
| 90 | widget will automatically become visible without needing a <a href="qwidget.html#show">show</a>()
|
|---|
| 91 | call. (This differs from every other Qt widget container. We
|
|---|
| 92 | recommend calling show() anyway since we hope to fix this anomaly
|
|---|
| 93 | in a future release.)
|
|---|
| 94 | <p> QToolBars, like QDockWindows, are located in <a href="qdockarea.html">QDockArea</a>s or
|
|---|
| 95 | float as top-level windows. QMainWindow provides four QDockAreas
|
|---|
| 96 | (top, left, right and bottom). When you create a new toolbar (as
|
|---|
| 97 | in the example above) as a child of a QMainWindow the toolbar will
|
|---|
| 98 | be added to the top dock area. You can move it to another dock
|
|---|
| 99 | area (or float it) by calling <a href="qmainwindow.html#moveDockWindow">QMainWindow::moveDockWindow</a>(). QDock
|
|---|
| 100 | areas lay out their windows in <a href="qdockarea.html#lines">Lines</a>.
|
|---|
| 101 | <p> If the main window is resized so that the area occupied by the
|
|---|
| 102 | toolbar is too small to show all its widgets a little arrow button
|
|---|
| 103 | (which looks like a right-pointing chevron, '»') will appear
|
|---|
| 104 | at the right or bottom of the toolbar depending on its
|
|---|
| 105 | orientation. Clicking this button pops up a menu that shows the
|
|---|
| 106 | 'overflowing' items. QToolButtons are represented in the menu using
|
|---|
| 107 | their textLabel property, other <a href="qbutton.html">QButton</a> subclasses are represented
|
|---|
| 108 | using their text property, and QComboBoxes are represented as submenus,
|
|---|
| 109 | with the caption text being used in the submenu item.
|
|---|
| 110 | <p> Usually a toolbar will get precisely the space it needs. However,
|
|---|
| 111 | with <a href="qdockwindow.html#setHorizontalStretchable">setHorizontalStretchable</a>(), <a href="qdockwindow.html#setVerticalStretchable">setVerticalStretchable</a>() or
|
|---|
| 112 | <a href="#setStretchableWidget">setStretchableWidget</a>() you can tell the main window to expand the
|
|---|
| 113 | toolbar to fill all available space in the specified orientation.
|
|---|
| 114 | <p> The toolbar arranges its buttons either horizontally or vertically
|
|---|
| 115 | (see <a href="qdockwindow.html#orientation">orientation</a>() for details). Generally, <a href="qdockarea.html">QDockArea</a> will set the
|
|---|
| 116 | orientation correctly for you, but you can set it yourself with
|
|---|
| 117 | <a href="qdockwindow.html#setOrientation">setOrientation</a>() and track any changes by connecting to the
|
|---|
| 118 | <a href="qdockwindow.html#orientationChanged">orientationChanged</a>() signal.
|
|---|
| 119 | <p> You can use the <a href="#clear">clear</a>() method to remove all items from a toolbar.

| 127 |
|

| 128 | <b>This function is obsolete.</b> It is provided to keep old source working. We strongly advise against using it in new code.

|
|---|
| 131 | </h3>
|
|---|
| 132 | Constructs an empty horizontal toolbar.
|
|---|
| 133 | <p> The toolbar is called <em>name</em> and is a child of <em>parent</em> and is
|
|---|
| 134 | managed by <em>mainWindow</em>. The <em>label</em> and <em>newLine</em> parameters
|
|---|
| 135 | are passed straight to <a href="qmainwindow.html#addDockWindow">QMainWindow::addDockWindow</a>(). <em>name</em> and
|
|---|
| 136 | the widget flags <em>f</em> are passed on to the <a href="qdockwindow.html">QDockWindow</a> constructor.
|
|---|
| 137 | <p> Use this constructor if you want to create torn-off (undocked,
|
|---|
| 138 | floating) toolbars or toolbars in the <a href="qstatusbar.html">status
|
|---|
| 139 | bar</a>.

|
|---|
| 142 | </h3>
|
|---|
| 143 | This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
|
|---|
| 144 | <p> Constructs an empty toolbar called <em>name</em>, with parent <em>parent</em>,
|
|---|
| 145 | in its <em>parent</em>'s top dock area, without any label and without
|
|---|
| 146 | requiring a newline.

| 147 |
|

| 148 | <h3 class=fn>void <a name="addSeparator"></a>QToolBar::addSeparator ()
|
|---|
| 149 | </h3>
|

|---|
| 157 | <h3 class=fn><a href="qstring.html">QString</a> <a name="label"></a>QToolBar::label () const
|

| 160 | <h3 class=fn><a href="qmainwindow.html">QMainWindow</a> * <a name="mainWindow"></a>QToolBar::mainWindow () const
|
|---|
| 161 | </h3>

|
|---|
| 168 | </h3>
|
|---|
| 169 | Sets the widget <em>w</em> to be expanded if this toolbar is requested
|
|---|
| 170 | to stretch.
|
|---|
| 171 | <p> The request to stretch might occur because <a href="qmainwindow.html">QMainWindow</a>
|
|---|
| 172 | right-justifies the dock area the toolbar is in, or because this
|
|---|
| 173 | toolbar's <a href="qdockwindow.html#isVerticalStretchable">isVerticalStretchable</a>() or <a href="qdockwindow.html#isHorizontalStretchable">isHorizontalStretchable</a>() is
|
|---|
| 174 | set to TRUE.
|
|---|
| 175 | <p> If you call this function and the toolbar is not yet stretchable,

| 176 | setStretchable() is called.
