The possibles states of an object.
Indicates an invalid state | |
Indicates a window is currently the active window | |
Indicates that the object is armed | |
Indicates the current object is busy | |
Indicates this object is currently checked | |
Indicates this object is collapsed | |
Indicates the user interface object corresponding to this object no longer exists | |
Indicates the user can change the contents of this object | |
Indicates that this object is enabled | |
Indicates this object allows progressive disclosure of its children | |
Indicates this object its expanded | |
Indicates this object can accept keyboard focus, which means all events resulting from typing on the keyboard will normally be passed to it when it has focus | |
Indicates this object currently has the keyboard focus | |
Indicates the orientation of thsi object is horizontal | |
Indicates this object is minimized and is represented only by an icon | |
Indicates something must be done with this object before the user can interact with an object in a different window | |
Indicates this (text) object can contain multiple lines of text | |
Indicates this object allows more than one of its children to be selected at the same time | |
Indicates this object paints every pixel within its rectangular region | |
Indicates this object is currently pressed | |
Indicates the size of this object is not fixed | |
Indicates this object is the child of an object that allows its children to be selected and that this child is one of those children that can be selected | |
Indicates this object is the child of an object that allows its children to be selected and that this child is one of those children that has been selected | |
Indicates this object is sensitive | |
Indicates this object, the object's parent, the object's parent's parent, and so on, are all visible | |
Indicates this (text) object can contain only a single line of text | |
Indicates that the index associated with this object has changed since the user accessed the object | |
Indicates this object is transient | |
Indicates the orientation of this object is vertical | |
Indicates this object is visible | |
Indicates that "active-descendant-changed" event is sent when children become 'active' (i.e. are selected or navigated to onscreen). Used to prevent need to enumerate all children in very large containers, like tables. | |
Indicates that a check box is in a state other than checked or not checked. | |
Indicates that an object is truncated, e.g. a text value in a speradsheet cell. | |
Indicates that explicit user interaction with an object is required by the user interface, e.g. a required field in a "web-form" interface. | |
Indicates that the object has encountered an error condition due to failure of input validation. For instance, a form control may acquire this state in response to invalid or malformed user input. | |
Indicates that the object may exhibit "typeahead" behavior in response to user keystrokes, e.g. one keystroke may result in the insertion of several characters into an entry, or result in the auto-selection of an item in a list. This state supplants SPI_ROLE_AUTOCOMPLETE .
|
|
Indicates that the object in question supports text selection. It should only be exposed on objects which implement the Text interface, in order to distinguish this state from SPI_STATE_SELECTABLE , which infers that the object in question is a selectable child of an object which implements Selection. While similar, text selection and subelement selection are distinct operations.
|
|
Indicates that the object is the "default" active component, i.e. the object which is activated by an end-user press of the "Enter" or "Return" key. Typically a "close" or "submit" button. | |
Indicates that the object (typically a hyperlink) has already been 'activated', and/or its backing data has already been downloaded, rendered, or otherwise "visited". | |
Not a valid state, used for finding end of enumeration |
struct AccessibleStateSet { guint ref_count; GArray *states; };
An opaque structure representing an accessible object's state, which can then be queried via AccessibleStateSet APIs.
An AccessibleStateSet determines a component's state set. It is composed of a set of AccessibleState values.
void AccessibleStateSet_ref (AccessibleStateSet *obj);
Increment the reference count for an AccessibleStateSet object.
|
a pointer to the AccessibleStateSet object on which to operate. |
void AccessibleStateSet_unref (AccessibleStateSet *obj);
Decrement the reference count for an AccessibleStateSet object.
|
a pointer to the AccessibleStateSet object on which to operate. |
void AccessibleStateSet_add (AccessibleStateSet *obj, AccessibleState state);
Add a particular AccessibleState to an AccessibleStateSet (i.e. set the given state to TRUE in the stateset.
|
a pointer to the AccessibleStateSet object on which to operate. |
|
an AccessibleState to be added to the specified AccessibleStateSet |
AccessibleStateSet * AccessibleStateSet_compare (AccessibleStateSet *obj, AccessibleStateSet *obj2);
Determine the differences between two instances of AccessibleStateSet.
Not Yet Implemented.
.
see
AccessibleStateSet_equals()
.
|
a pointer to the first AccessibleStateSet object on which to operate. |
|
a pointer to the second AccessibleStateSet object on which to operate. |
Returns : |
an AccessibleStateSet object containing all states contained on one of the two sets but not the other. |
SPIBoolean AccessibleStateSet_contains (AccessibleStateSet *obj, AccessibleState state);
Determine whether a given AccessibleStateSet includes a given state; that is,
whether state
is true for the stateset in question.
|
a pointer to the AccessibleStateSet object on which to operate. |
|
an AccessibleState for which the specified AccessibleStateSet will be queried. |
Returns : |
TRUE if state is true/included in the given AccessibleStateSet,
otherwise FALSE.
|
SPIBoolean AccessibleStateSet_equals (AccessibleStateSet *obj, AccessibleStateSet *obj2);
Determine whether two instances of AccessibleStateSet are equivalent (i.e. consist of the same AccessibleStates). Useful for checking multiple state variables at once; construct the target state then compare against it.
see
AccessibleStateSet_compare()
.
|
a pointer to the first AccessibleStateSet object on which to operate. |
|
a pointer to the second AccessibleStateSet object on which to operate. |
Returns : |
TRUE if the two AccessibleStateSets are equivalent, otherwise FALSE. |
SPIBoolean AccessibleStateSet_isEmpty (AccessibleStateSet *obj);
Determine whether a given AccessibleStateSet is the empty set.
|
a pointer to the AccessibleStateSet object on which to operate. |
Returns : |
TRUE if the given AccessibleStateSet contains no (true) states, otherwise FALSE. |
void AccessibleStateSet_remove (AccessibleStateSet *obj, AccessibleState state);
Remove a particular AccessibleState to an AccessibleStateSet (i.e. set the given state to FALSE in the stateset.)
|
a pointer to the AccessibleStateSet object on which to operate. |
|
an AccessibleState to be removed from the specified AccessibleStateSet |
