|
|
|
|
|
|
The TQAccessibleInterface class defines an interface that exposes information about accessible objects.
|
|
<p>
|
|
<p>See also <a href="misc.html">Miscellaneous Classes</a>.

|
|
<h3 class=fn>int <a name="childCount"></a>TQAccessibleInterface::childCount () const<tt> [pure virtual]</tt>
|
|
</h3>
|
|
|
|
<p> Returns the number of children that belong to this object. A child
|
|
can provide accessibility information on it's own (e.g. a child
|
|
widget), or be a sub-element of this accessible object.
|
|
<p> All objects provide this information.
|
|
<p> <p>See also <a href="#queryChild">queryChild</a>().
|
|
|
|
<h3 class=fn>void <a name="clearSelection"></a>TQAccessibleInterface::clearSelection ()<tt> [pure virtual]</tt>
|
|
</h3>
|
|
|
|
<p> Removes any selection from the object.
|
|
<p> <p>See also <a href="#setSelected">setSelected</a>().
|
|
|
|
<h3 class=fn>int <a name="controlAt"></a>TQAccessibleInterface::controlAt ( int x, int y ) const<tt> [pure virtual]</tt>
|
|
</h3>
|
|
|
|
<p> Returns the ID of the child that contains the screen coordinates
|
|
(<em>x</em>, <em>y</em>). This function returns 0 if the point is positioned
|
|
on the object itself. If the tested point is outside the
|
|
boundaries of the object this function returns -1.
|
|
<p> All visual objects provide this information.
|
|
|
|
<h3 class=fn>bool <a name="doDefaultAction"></a>TQAccessibleInterface::doDefaultAction ( int control )<tt> [pure virtual]</tt>
|
|
</h3>
|
|
|
|
<p> Calling this function performs the default action of the child
|
|
object specified by <em>control</em>, or the default action of the
|
|
object itself if <em>control</em> is 0.
|
|
|
|
<h3 class=fn>bool <a name="isValid"></a>TQAccessibleInterface::isValid () const<tt> [pure virtual]</tt>
|
|
</h3>
|
|
|
|
<p> Returns TRUE if all the data necessary to use this interface
|
|
implementation is valid (e.g. all pointers are non-null),
|
|
otherwise returns FALSE.
|
|
|
|
<h3 class=fn>int <a name="navigate"></a>TQAccessibleInterface::navigate ( <a href="ntqaccessible.html#NavDirection-enum">NavDirection</a> direction, int startControl ) const<tt> [pure virtual]</tt>
|
|
</h3>
|
|
|
|
<p> This function traverses to another object, or to a sub-element of
|
|
the current object. <em>direction</em> specifies in which direction to
|
|
navigate, and <em>startControl</em> specifies the start point of the
|
|
navigation, which is either 0 if the navigation starts at the
|
|
object itself, or an ID of one of the object's sub-elements.
|
|
<p> The function returns the ID of the sub-element located in the <em>direction</em> specified. If there is nothing in the navigated <em>direction</em>, this function returns -1.
|
|
<p> All objects support navigation.
|
|
|
|
<h3 class=fn>TQRESULT <a name="queryChild"></a>TQAccessibleInterface::queryChild ( int control, <a href="qaccessibleinterface.html">TQAccessibleInterface</a> ** iface ) const<tt> [pure virtual]</tt>
|
|
</h3>
|
|
|
|
<p> Sets <em>iface</em> to point to the implementation of the
|
|
TQAccessibleInterface for the child specified with <em>control</em>. If
|
|
the child doesn't provide accessibility information on it's own,
|
|
the value of <em>iface</em> is set to 0. For those elements, this
|
|
object is responsible for exposing the child's properties.
|
|
<p> All objects provide this information.
|
|
<p> <p>See also <a href="#childCount">childCount</a>() and <a href="#queryParent">queryParent</a>().
|
|
|
|
<h3 class=fn>TQRESULT <a name="queryParent"></a>TQAccessibleInterface::queryParent ( <a href="qaccessibleinterface.html">TQAccessibleInterface</a> ** iface ) const<tt> [pure virtual]</tt>
|
|
</h3>
|
|
|
|
<p> Sets <em>iface</em> to point to the implementation of the
|
|
TQAccessibleInterface for the parent object, or to 0 if there is
|
|
no such implementation or object.
|
|
<p> All objects provide this information.
|
|
<p> <p>See also <a href="#queryChild">queryChild</a>().
|
|
|
|
<h3 class=fn><a href="tqrect.html">TQRect</a> <a name="rect"></a>TQAccessibleInterface::rect ( int control ) const<tt> [pure virtual]</tt>
|
|
</h3>
|
|
|
|
<p> Returns the location of the child specified with <em>control</em> in
|
|
screen coordinates. This function returns the location of the
|
|
object itself if <em>control</em> is 0.
|
|
<p> All visual objects provide this information.
|
|
|
|
<h3 class=fn><a href="ntqaccessible.html#Role-enum">Role</a> <a name="role"></a>TQAccessibleInterface::role ( int control ) const<tt> [pure virtual]</tt>
|
|
</h3>
|
|
|
|
<p> Returns the role of the object if <em>control</em> is 0, or the role of
|
|
the object's sub-element with ID <em>control</em>. The role of an object
|
|
is usually static. All accessible objects have a role.
|
|
<p> <p>See also <a href="#text">text</a>(), <a href="#state">state</a>(), and <a href="#selection">selection</a>().
|
|
|
|
<h3 class=fn><a href="tqmemarray.html">TQMemArray</a><int> <a name="selection"></a>TQAccessibleInterface::selection () const<tt> [pure virtual]</tt>
|
|
</h3>
|
|
|
|
<p> Returns the list of all the element IDs that are selected.
|
|
<p> <p>See also <a href="#text">text</a>(), <a href="#role">role</a>(), and <a href="#state">state</a>().
|
|
|
|
<h3 class=fn>bool <a name="setFocus"></a>TQAccessibleInterface::setFocus ( int control )<tt> [pure virtual]</tt>
|
|
</h3>
|
|
|
|
<p> Gives the focus to the child object specified by <em>control</em>, or to
|
|
the object itself if <em>control</em> is 0.
|
|
<p> Returns TRUE if the focus could be set; otherwise returns FALSE.
|
|
|
|
<h3 class=fn>bool <a name="setSelected"></a>TQAccessibleInterface::setSelected ( int control, bool on, bool extend )<tt> [pure virtual]</tt>
|
|
</h3>
|
|
|
|
<p> Sets the selection of the child object with ID <em>control</em> to <em>on</em>. If <em>extend</em> is TRUE, all child elements between the focused
|
|
item and the specified child object have their selection set to <em>on</em>.
|
|
<p> Returns TRUE if the selection could be set; otherwise returns
|
|
FALSE.
|
|
<p> <p>See also <a href="#setFocus">setFocus</a>() and <a href="#clearSelection">clearSelection</a>().
|
|
|
|
<h3 class=fn>void <a name="setText"></a>TQAccessibleInterface::setText ( <a href="ntqaccessible.html#Text-enum">Text</a> t, int control, const <a href="tqstring.html">TQString</a> & text )<tt> [pure virtual]</tt>
|
|
</h3>
|
|
|
|
<p> Sets the text property <em>t</em> of the child object <em>control</em> to <em>text</em>. If <em>control</em> is 0, the text property of the object itself
|
|
is set.
|
|
|
|
<h3 class=fn><a href="ntqaccessible.html#State-enum">State</a> <a name="state"></a>TQAccessibleInterface::state ( int control ) const<tt> [pure virtual]</tt>
|
|
</h3>
|
|
|
|
<p> Returns the current state of the object if <em>control</em> is 0, or the
|
|
state of the object's sub-element element with ID <em>control</em>. All
|
|
objects have a state.
|
|
<p> <p>See also <a href="#text">text</a>(), <a href="#role">role</a>(), and <a href="#selection">selection</a>().
|
|
|
|
<h3 class=fn><a href="tqstring.html">TQString</a> <a name="text"></a>TQAccessibleInterface::text ( <a href="ntqaccessible.html#Text-enum">Text</a> t, int control ) const<tt> [pure virtual]</tt>
|
|
</h3>
|
|
|
|
<p> Returns a string property <em>t</em> of the child object specified by <em>control</em>, or the string property of the object itself if <em>control</em>
|
|
is 0.
|
|
<p> The <em>Name</em> is a string used by clients to identify, find or
|
|
announce an accessible object for the user. All objects must have
|
|
a name that is unique within their container.
|
|
<p> An accessible object's <em>Description</em> provides textual information
|
|
about an object's visual appearance. The description is primarily
|
|
used to provide greater context for low-vision or blind users, but
|
|
is also used for context searching or other applications. Not all
|
|
objects have a description. An "OK" button would not need a
|
|
description, but a toolbutton that shows a picture of a smiley
|
|
would.
|
|
<p> The <em>Value</em> of an accessible object represents visual information
|
|
contained by the object, e.g. the text in a line edit. Usually,
|
|
the value can be modified by the user. Not all objects have a
|
|
value, e.g. static text labels don't, and some objects have a
|
|
state that already is the value, e.g. toggle buttons.
|
|
<p> The <em>Help</em> text provides information about the function and
|
|
usage of an accessible object. Not all objects provide this
|
|
information.
|
|
<p> An accessible object's <em>DefaultAction</em> describes the object's
|
|
primary method of manipulation, and should be a verb or a short
|
|
phrase, e.g. "Press" for a button.
|
|
<p> The accelerator is a keyboard shortcut that activates the default
|
|
action of the object. A keyboard shortcut is the underlined
|
|
character in the text of a menu, menu item or control, and is
|
|
either the character itself, or a combination of this character
|
|
and a modifier key like ALT, CTRL or SHIFT. Command controls like
|
|
tool buttons also have shortcut keys and usually display them in
|
|
their tooltip.
|
|
