|
|
|
|
|
|
The TQAction class provides an abstract user interface
|
|
action that can appear both in menus and tool bars.
|
|
<p>
|
|
|
|
|
|
<p> In GUI applications many commands can be invoked via a menu
|
|
option, a toolbar button and a keyboard accelerator. Since the
|
|
same action must be performed regardless of how the action was
|
|
invoked, and since the menu and toolbar should be kept in sync, it
|
|
is useful to represent a command as an <em>action</em>. An action can be
|
|
added to a menu and a toolbar and will automatically keep them in
|
|
sync. For example, if the user presses a Bold toolbar button the
|
|
Bold menu item will automatically be checked.
|
|
<p> A TQAction may contain an icon, a menu text, an accelerator, a
|
|
status text, a whats this text and a tool tip. Most of these can
|
|
be set in the constructor. They can also be set independently with
|
|
<a href="#setIconSet">setIconSet</a>(), <a href="#setText">setText</a>(), <a href="#setMenuText">setMenuText</a>(), <a href="#setToolTip">setToolTip</a>(),
|
|
<a href="#setStatusTip">setStatusTip</a>(), <a href="#setWhatsThis">setWhatsThis</a>() and <a href="#setAccel">setAccel</a>().
|
|
<p> An action may be a toggle action e.g. a Bold toolbar button, or a
|
|
command action, e.g. 'Open File' to invoke an open file dialog.
|
|
Toggle actions emit the <a href="#toggled">toggled</a>() signal when their state changes.
|
|
Both command and toggle actions emit the <a href="#activated">activated</a>() signal when
|
|
they are invoked. Use <a href="#setToggleAction">setToggleAction</a>() to set an action's toggled
|
|
status. To see if an action is a toggle action use
|
|
<a href="#isToggleAction">isToggleAction</a>(). A toggle action may be "on", <a href="#isOn">isOn</a>() returns
|
|
TRUE, or "off", isOn() returns FALSE.
|
|
<p> Actions are added to widgets (menus or toolbars) using <a href="#addTo">addTo</a>(),
|
|
and removed using <a href="#removeFrom">removeFrom</a>().
|
|
<p> Once a TQAction has been created it should be added to the relevant
|
|
menu and toolbar and then connected to the slot which will perform
|
|
the action. For example:
|
|
<p>
|
|
|
|
<pre> fileOpenAction = new TQAction( TQPixmap( fileopen ), "&Open...",
|
|
CTRL+Key_O, this, "open" );
|
|
<a href="ntqobject.html#connect">connect</a>( fileOpenAction, TQ_SIGNAL( <a href="#activated">activated</a>() ) , this, TQ_SLOT( choose() ) );
|
|
</pre>
|
|
<p> We create a "File Save" action with a menu text of "&Save" and
|
|
<em>Ctrl+S</em> as the keyboard accelerator. We connect the
|
|
fileSaveAction's <a href="#activated">activated</a>() signal to our own save() slot. Note
|
|
that at this point there is no menu or toolbar action, we'll add
|
|
them next:
|
|
<p> <pre> <a href="ntqtoolbar.html">TQToolBar</a> * fileTools = new <a href="ntqtoolbar.html">TQToolBar</a>( this, "file operations" );
|
|
</pre><pre> fileSaveAction-><a href="#addTo">addTo</a>( fileTools );
|
|
</pre><pre> <a href="ntqpopupmenu.html">TQPopupMenu</a> * file = new <a href="ntqpopupmenu.html">TQPopupMenu</a>( this );
|
|
<a href="ntqmainwindow.html#menuBar">menuBar</a>()->insertItem( "&File", file );
|
|
</pre><pre> fileSaveAction-><a href="#addTo">addTo</a>( file );
|
|
</pre>
|
|
<p> We create a toolbar and add our fileSaveAction to it. Similarly we
|
|
create a menu, add a top-level menu item, and add our
|
|
fileSaveAction.
|
|
<p> We recommend that actions are created as children of the window
|
|
that they are used in. In most cases actions will be children of
|
|
the application's main window.
|
|
<p> To prevent recursion, don't create an action as a child of a
|
|
widget that the action is later added to.

a widget, or an action group whose parent is a widget.
|
|
<p> The action uses a stripped version of <em>menuText</em> (e.g. "&Menu
|
|
Option..." becomes "Menu Option") as descriptive text for
|
|
toolbuttons. You can override this by setting a specific
|
|
description with <a href="#setText">setText</a>(). The same text and <em>accel</em> will be

<p> Call <a href="#setToggleAction">setToggleAction</a>(TRUE) to make the action a toggle action.

<h3 class=fn><a href="ntqkeysequence.html">TQKeySequence</a> <a name="accel-prop"></a>accel</h3>
|
|
<p>This property holds the action's accelerator key.
|
|
<p>The keycodes can be found in <a href="ntqt.html#Key-enum">TQt::Key</a> and <a href="ntqt.html#Modifier-enum">TQt::Modifier</a>. There
|
|
is no default accelerator key.
|
|
|

|
|
<h3 class=fn>bool <a name="enabled-prop"></a>enabled</h3>
|
|
<p>This property holds whether the action is enabled.
|
|
<p>Disabled actions can't be chosen by the user. They don't disappear
|
|
from the menu/tool bar but are displayed in a way which indicates
|
|
that they are unavailable, e.g. they might be displayed grayed
|
|
out.
|
|
<p> What's this? help on disabled actions is still available provided
|
|
the <a href="#whatsThis-prop">TQAction::whatsThis</a> property is set.
|
|
|
|
<p>Set this property's value with <a href="#setEnabled">setEnabled</a>() and get this property's value with <a href="#isEnabled">isEnabled</a>().
|
|
<h3 class=fn><a href="ntqiconset.html">TQIconSet</a> <a name="iconSet-prop"></a>iconSet</h3>
|
|
<p>This property holds the action's icon.
|
|
<p>The icon is used as the tool button icon and in the menu to the
|
|
left of the menu text. There is no default icon.
|
|
<p> If a null icon (<a href="ntqiconset.html#isNull">TQIconSet::isNull</a>() is passed into this function,
|
|
the icon of the action is cleared.
|
|
<p> (See the action/toggleaction/toggleaction.cpp example.)
|
|
<p>
|
|
<p>Set this property's value with <a href="#setIconSet">setIconSet</a>() and get this property's value with <a href="#iconSet">iconSet</a>().
|
|
<h3 class=fn><a href="ntqstring.html">TQString</a> <a name="menuText-prop"></a>menuText</h3>
|
|
<p>This property holds the action's menu text.
|
|
<p>If the action is added to a menu the menu option will consist of
|
|
the icon (if there is one), the menu text and the accelerator (if
|
|
there is one). If the menu text is not explicitly set in the
|
|
constructor or by using <a href="#setMenuText">setMenuText</a>() the action's description
|
|
text will be used as the menu text. There is no default menu text.
|
|
<p> <p>See also <a href="#text-prop">text</a>.
|
|
|
|
<p>Set this property's value with <a href="#setMenuText">setMenuText</a>() and get this property's value with <a href="#menuText">menuText</a>().
|
|
<h3 class=fn>bool <a name="on-prop"></a>on</h3>
|
|
<p>This property holds whether a toggle action is on.
|
|
<p>This property is always on (TRUE) for command actions and
|
|
<a href="qactiongroup.html">TQActionGroup</a>s; <a href="#setOn">setOn</a>() has no effect on them. For action's
|
|
where <a href="#isToggleAction">isToggleAction</a>() is TRUE, this property's default value is
|
|
off (FALSE).
|
|
<p> <p>See also <a href="#toggleAction-prop">toggleAction</a>.
|
|
|
|
<p>Set this property's value with <a href="#setOn">setOn</a>() and get this property's value with <a href="#isOn">isOn</a>().
|
|
<h3 class=fn><a href="ntqstring.html">TQString</a> <a name="statusTip-prop"></a>statusTip</h3>
|
|
<p>This property holds the action's status tip.
|
|
<p>The statusTip is displayed on all status bars that this action's
|
|
toplevel parent widget provides.
|
|
<p> If no status tip is defined, the action uses the tool tip text.
|
|
<p> There is no default statusTip text.
|
|
<p> <p>See also <a href="#statusTip-prop">statusTip</a> and <a href="#toolTip-prop">toolTip</a>.
|
|
|
|
<p>Set this property's value with <a href="#setStatusTip">setStatusTip</a>() and get this property's value with <a href="#statusTip">statusTip</a>().
|
|
<h3 class=fn><a href="ntqstring.html">TQString</a> <a name="text-prop"></a>text</h3>
|
|
<p>This property holds the action's descriptive text.
|
|
<p>If <a href="ntqmainwindow.html#usesTextLabel-prop">TQMainWindow::usesTextLabel</a> is TRUE, the text appears as a
|
|
label in the relevant tool button. It also serves as the default
|
|
text in menus and tool tips if these have not been specifically
|
|
defined. There is no default text.

|
|
<h3 class=fn>bool <a name="toggleAction-prop"></a>toggleAction</h3>
|
|
<p>This property holds whether the action is a toggle action.
|
|
<p>A toggle action is one which has an on/off state. For example a
|
|
Bold toolbar button is either on or off. An action which is not a
|
|
toggle action is a command action; a command action is simply
|
|
executed, e.g. file save. This property's default is FALSE.
|
|
<p> In some situations, the state of one toggle action should depend
|
|
on the state of others. For example, "Left Align", "Center" and
|
|
"Right Align" toggle actions are mutually exclusive. To achieve
|
|
exclusive toggling, add the relevant toggle actions to a
|
|
<a href="qactiongroup.html">TQActionGroup</a> with the <a href="qactiongroup.html#exclusive-prop">TQActionGroup::exclusive</a> property set to
|
|
TRUE.

<p>Set this property's value with <a href="#setToggleAction">setToggleAction</a>() and get this property's value with <a href="#isToggleAction">isToggleAction</a>().
|
|
<h3 class=fn><a href="ntqstring.html">TQString</a> <a name="toolTip-prop"></a>toolTip</h3>
|
|
<p>This property holds the action's tool tip.
|
|
<p>This text is used for the tool tip. If no status tip has been set
|
|
the tool tip will be used for the status tip.
|
|
<p> If no tool tip is specified the action's text is used, and if that
|
|
hasn't been specified the description text is used as the tool tip
|
|
text.
|
|
<p> There is no default tool tip text.
|
|
<p> <p>See also <a href="#statusTip-prop">statusTip</a> and <a href="#accel-prop">accel</a>.
|
|
|
|
<p>Set this property's value with <a href="#setToolTip">setToolTip</a>() and get this property's value with <a href="#toolTip">toolTip</a>().
|
|
<h3 class=fn>bool <a name="visible-prop"></a>visible</h3>
|
|
<p>This property holds whether the action can be seen (e.g. in menus and toolbars).
|
|
<p>If <em>visible</em> is TRUE the action can be seen (e.g. in menus and
|
|
toolbars) and chosen by the user; if <em>visible</em> is FALSE the
|
|
action cannot be seen or chosen by the user.
|
|
<p> Actions which are not visible are <em>not</em> grayed out; they do not
|
|
appear at all.
|
|
|
|
<p>Set this property's value with <a href="#setVisible">setVisible</a>() and get this property's value with <a href="#isVisible">isVisible</a>().
|
|
<h3 class=fn><a href="ntqstring.html">TQString</a> <a name="whatsThis-prop"></a>whatsThis</h3>
|
|
<p>This property holds the action's "What's This?" help text.
|
|
<p>The whats this text is used to provide a brief description of the
|
|
action. The text may contain rich text (HTML-like tags -- see
|
|
<a href="ntqstylesheet.html">TQStyleSheet</a> for the list of supported tags). There is no default
|
|
"What's This" text.
|
|
<p> <p>See also <a href="ntqwhatsthis.html">TQWhatsThis</a>.
|
|
|
|
<p>Set this property's value with <a href="#setWhatsThis">setWhatsThis</a>() and get this property's value with <a href="#whatsThis">whatsThis</a>().
