|
|---|
| 76 |
|
|---|
| 77 |
|
|---|
| 78 | The QToolTip class provides tool tips (balloon help) for
|
|---|
| 79 | any widget or rectangular part of a widget.
|
|---|
| 80 | <p>
|
|---|
| 81 |
|
|---|
| 82 | <p> The tip is a short, single line of text reminding the user of the
|
|---|
| 83 | widget's or rectangle's function. It is drawn immediately below
|
|---|
| 84 | the region in a distinctive black-on-yellow combination.
|
|---|
| 85 | <p> The tip can be any Rich-Text formatted string.
|
|---|
| 86 | <p> <a href="qtooltipgroup.html">QToolTipGroup</a> provides a way for tool tips to display another text
|
|---|
| 87 | elsewhere (most often in a <a href="qstatusbar.html">status bar</a>).
|
|---|
| 88 | <p> At any point in time, QToolTip is either dormant or active. In
|
|---|
| 89 | dormant mode the tips are not shown and in active mode they are.
|
|---|
| 90 | The mode is global, not particular to any one widget.
|
|---|
| 91 | <p> QToolTip switches from dormant to active mode when the user hovers
|
|---|
| 92 | the mouse on a tip-equipped region for a second or so and remains
|
|---|
| 93 | active until the user either clicks a mouse button, presses a key,
|
|---|
| 94 | lets the mouse hover for five seconds or moves the mouse outside
|
|---|
| 95 | <em>all</em> tip-equipped regions for at least a second.
|
|---|
| 96 | <p> The QToolTip class can be used in three different ways:
|
|---|
| 97 | <ol type=1>
|
|---|
| 98 | <li> Adding a tip to an entire widget.
|
|---|
| 99 | <li> Adding a tip to a fixed rectangle within a widget.
|
|---|
| 100 | <li> Adding a tip to a dynamic rectangle within a widget.
|
|---|
| 101 | </ol>
|
|---|
| 102 | <p> To add a tip to a widget, call the <em>static</em> function
|
|---|
| 103 | <a href="#add">QToolTip::add</a>() with the widget and tip as arguments:
|
|---|
| 104 | <p> <pre>
|
|---|
| 105 | QToolTip::<a href="#add">add</a>( quitButton, "Leave the application" );
|
|---|
| 106 | </pre>
|
|---|
| 107 |
|
|---|
| 108 | <p> This is the simplest and most common use of QToolTip. The tip
|
|---|
| 109 | will be deleted automatically when <em>quitButton</em> is deleted, but
|
|---|
| 110 | you can remove it yourself, too:
|
|---|
| 111 | <p> <pre>
|
|---|
| 112 | QToolTip::<a href="#remove">remove</a>( quitButton );
|
|---|
| 113 | </pre>
|
|---|
| 114 |
|
|---|
| 115 | <p> You can also display another text (typically in a <a href="qstatusbar.html">status bar),</a> courtesy of <a href="qtooltipgroup.html">QToolTipGroup</a>. This example
|
|---|
| 116 | assumes that <em>grp</em> is a <tt>QToolTipGroup *</tt> and is already
|
|---|
| 117 | connected to the appropriate status bar:
|
|---|
| 118 | <p> <pre>
|
|---|
| 119 | QToolTip::<a href="#add">add</a>( quitButton, "Leave the application", grp,
|
|---|
| 120 | "Leave the application, prompting to save if necessary" );
|
|---|
| 121 | QToolTip::<a href="#add">add</a>( closeButton, "Close this window", grp,
|
|---|
| 122 | "Close this window, prompting to save if necessary" );
|
|---|
| 123 | </pre>
|
|---|
| 124 |
|
|---|
| 125 | <p> To add a tip to a fixed rectangle within a widget, call the static
|
|---|
| 126 | function <a href="#add">QToolTip::add</a>() with the widget, rectangle and tip as
|
|---|
| 127 | arguments. (See the <a href="tooltip-example.html">tooltip/tooltip.cpp</a> example.) Again, you
|
|---|
| 128 | can supply a <tt>QToolTipGroup *</tt> and another text if you want.
|
|---|
| 129 | <p> Both of these are one-liners and cover the majority of cases. The
|
|---|
| 130 | third and most general way to use QToolTip requires you to
|
|---|
| 131 | reimplement a pure virtual function to decide whether to pop up a
|
|---|
| 132 | tool tip. The <a href="tooltip-example.html">tooltip/tooltip.cpp</a> example demonstrates this
|
|---|
| 133 | too. This mode can be used to implement tips for text that can
|
|---|
| 134 | move as the user scrolls, for example.
|
|---|
| 135 | <p> To use QToolTip like this, you must subclass QToolTip and
|
|---|
| 136 | reimplement <a href="#maybeTip">maybeTip</a>(). QToolTip calls maybeTip() when a tip
|
|---|
| 137 | should pop up, and maybeTip() decides whether to show a tip.
|
|---|
| 138 | <p> Tool tips can be globally disabled using
|
|---|
| 139 | <a href="#setGloballyEnabled">QToolTip::setGloballyEnabled</a>() or disabled in groups with
|
|---|
| 140 | <a href="qtooltipgroup.html#setEnabled">QToolTipGroup::setEnabled</a>().
|
|---|
| 141 | <p> You can retrieve the text of a tooltip for a given position within
|
|---|
| 142 | a widget using <a href="#textFor">textFor</a>().
|
|---|
| 143 | <p> The global tooltip font and palette can be set with the static
|
|---|
| 144 | <a href="#setFont">setFont</a>() and <a href="#setPalette">setPalette</a>() functions respectively.
|
|---|

|

| 240 |
|
|---|
| 241 | <p> This pure virtual function is half of the most versatile interface
|
|---|
| 242 | QToolTip offers.
|
|---|
| 243 | <p> It is called when there is a possibility that a tool tip should be
|
|---|
| 244 | shown and must decide whether there is a tool tip for the point <em>p</em> in the widget that this QToolTip object relates to. If so,
|
|---|
| 245 | <a href="#maybeTip">maybeTip</a>() must call <a href="#tip">tip</a>() with the rectangle the tip applies to,
|
|---|
| 246 | the tip's text and optionally the <a href="qtooltipgroup.html">QToolTipGroup</a> details and the
|
|---|
| 247 | geometry in screen coordinates.
|
|---|
| 248 | <p> <em>p</em> is given in that widget's local coordinates. Most maybeTip()
|
|---|
| 249 | implementations will be of the form:
|
|---|
| 250 | <p> <pre>
|
|---|
| 251 | if ( <something> ) {
|
|---|
| 252 | <a href="#tip">tip</a>( <something>, <something> );
|
|---|
| 253 | }
|
|---|
| 254 | </pre>
|
|---|
| 255 |
|
|---|
| 256 | <p> The first argument to tip() (a rectangle) must encompass <em>p</em>,
|
|---|
| 257 | i.e. the tip must apply to the current mouse position; otherwise
|
|---|
| 258 | QToolTip's operation is undefined.
|
|---|
| 259 | <p> Note that the tip will disappear once the mouse moves outside the
|
|---|
| 260 | rectangle you give to tip(), and will not reappear if the mouse
|
