509 | \brief The QtButtonPropertyBrowser class provides a drop down QToolButton
|
---|
510 | based property browser.
|
---|
511 |
|
---|
512 | A property browser is a widget that enables the user to edit a
|
---|
513 | given set of properties. Each property is represented by a label
|
---|
514 | specifying the property's name, and an editing widget (e.g. a line
|
---|
515 | edit or a combobox) holding its value. A property can have zero or
|
---|
516 | more subproperties.
|
---|
517 |
|
---|
518 | QtButtonPropertyBrowser provides drop down button for all nested
|
---|
519 | properties, i.e. subproperties are enclosed by a container associated with
|
---|
520 | the drop down button. The parent property's name is displayed as button text. For example:
|
---|
521 |
|
---|
522 | \image qtbuttonpropertybrowser.png
|
---|
523 |
|
---|
524 | Use the QtAbstractPropertyBrowser API to add, insert and remove
|
---|
525 | properties from an instance of the QtButtonPropertyBrowser
|
---|
526 | class. The properties themselves are created and managed by
|
---|
527 | implementations of the QtAbstractPropertyManager class.
