Member Function Documentation

YPropertyValue YPushButton::getProperty ( const string &  propertyName) [virtual]

Get a property. Reimplemented from YWidget.

This method may throw YUIPropertyExceptions.

Reimplemented from YWidget.

bool YPushButton::isDefaultButton ( ) const

Returns 'true' if this is the dialog's default button, i.e. the one button that gets activated if the user hits the [Return] key anywhere in the dialog.

bool YPushButton::isHelpButton ( ) const

Returns 'true' if this is a "Help" button.

When activated, a help button will traverse up its widget hierarchy and search for the topmost widget with a helpText() set and display that help text in a pop-up dialog (with a local event loop).

NOTE that this is only done during YDialog::waitForEvent() (i.e. in YCP UI::WaitForEvent(), UI::UserInput(), UI::TimeoutUserInput() ) and not during YDialog::pollEvent() (i.e. YCP UI::PollInput()) since displaying the help text will block the application until the user closes the help text.

string YPushButton::label ( ) const

Get the label (the text on the button).

const YPropertySet & YPushButton::propertySet ( ) [virtual]

Return this class's property set. This also initializes the property upon the first call.

Reimplemented from YWidget.

Reimplemented from YWidget.

YButtonRole YPushButton::role ( ) const

Return the role of this button.

void YPushButton::setDefaultButton ( bool  def = true) [virtual]

Make this button the default button.

Derived classes should reimplement this, but call this base class function in the overwritten function.

void YPushButton::setFunctionKey ( int  fkey_no) [virtual]

Assign a function key to this widget (1 for F1, 2 for F2, etc.; 0 for none)

Reimplemented from YWidget to map function keys to button roles.

Derived classes may want to overwrite this function, but they should call this base class function in the new function.

Reimplemented from YWidget.

void YPushButton::setHelpButton ( bool  helpButton = true) [virtual]

Make this button a help button.

Derived classes are free to reimplement this, but they should call this base class method in the overloaded function.

virtual void YPushButton::setIcon ( const string &  iconName) [inline, virtual]

Set this button's icon from an icon file in the UI's default icon directory. Clear the icon if the name is empty.

This default implementation does nothing. UIs that can handle icons can choose to overwrite this method.

void YPushButton::setLabel ( const string &  label) [virtual]

Set the label (the text on the button).

Derived classes are free to reimplement this, but they should call this base class method at the end of the overloaded function.

bool YPushButton::setProperty ( const string &  propertyName,
const YPropertyValue val 
) [virtual]

Set a property. Reimplemented from YWidget.

This function may throw YUIPropertyExceptions.

This function returns 'true' if the value was successfully set and 'false' if that value requires special handling (not in error cases: those are covered by exceptions).

Reimplemented from YWidget.

void YPushButton::setRole ( YButtonRole  role) [virtual]

Set a predefined role for this button.

This is important when the button is a child of a YButtonBox so the layout can be arranged according to the conventions of the current UI or desktop environment.

See YButtonBox.h for more details. YButtonRole is defined in YTypes.h

The default is YCustomButton, i.e., no predefined role. setFunctionKey() uses some heuristics to map function keys to buttons:

F10 -> YOkButton F9 -> YCancelButton F1 -> YHelpButton

Derived classes are free to reimplement this, but they should call this base class function in the overwritten function.

virtual void YPushButton::setShortcutString ( const string &  str) [inline, virtual]

Set the string of this widget that holds the keyboard shortcut.

Reimplemented from YWidget.

Reimplemented from YWidget.

virtual string YPushButton::shortcutString ( ) const [inline, virtual]

Get the string of this widget that holds the keyboard shortcut.

Reimplemented from YWidget.

Reimplemented from YWidget.

virtual const char* YPushButton::widgetClass ( ) const [inline, virtual]

Return a descriptive name of this widget class for logging, debugging etc.

Reimplemented from YWidget.
