Member Function Documentation

void CheckBox::EnableStatusChanged (  bool bIsEnabled )  [virtual]

Reimplemented from os::Control.

Point CheckBox::GetPreferredSize (  bool bLargest )  const [virtual]

Reimplemented from os::View.

bool CheckBox::Invoked (  Message * pcMessage )  [virtual]

Description: This member is called from Invoke() just before a message is sendt to the target. This allow classes that inherits from os::Invoker to add data to or otherwhice modify the message before it is sendt. The message can also be canceled entirely by returning false from this member. The message passed to Invoked() is a copy of the internal message or the message passed to Invoke() (if any) so any changes made here will not affect the internal message or the message passed to Invoke(). When this method returns the message will imidiatly be sendt to the target and then discarded (unless false is returned in which case the message is simply discarded). The default implementation of this member does nothing and return true. Parameters: pcMessage   Pointer to the message that is about to be sendt. You can do any modification you like to this message (but never delete it). Returns: Normally you should return true to indicate that the message should be sendt. You can however return false if you for some reason want to cancel the invokation. See also: Invoke(), SetMessage(), SetTarget() Author: Kurt Skauen ([email protected]) Reimplemented from os::Control.

void CheckBox::LabelChanged (  const std::string & cNewLabel )  [virtual]

Reimplemented from os::Control.

void CheckBox::MouseDown (  const Point & cPosition, uint32 nButtons )  [virtual]

Description: This member is called from the window thread whenever a mouse button is clicked above the view. You can overload this member if your view need to know about mouse-down events. A view will not automatically take focus when clicked so if you want that behaviour you must call MakeFocus() from an overloaded version of this member. The default implementation of this member will call MouseDown() on it's parent view if one exists. Parameters: cPosition   Mouse position in the views coordinate system at the time the mouse was pressed. nButtons   Index of the pressed button. Buttons start at 1 for the left button, 2 for the right button, 3 for the middle button. Additional buttons might be supported by the mouse driver and will then be assigned numbers from 4 and up. See also: MouseUp(), MouseMove(), WheelMoved() Author: Kurt Skauen ([email protected]) Reimplemented from os::View.

void CheckBox::MouseUp (  const Point & cPosition, uint32 nButtons, Message * pcData )  [virtual]

Description: This member is called from the window thread whenever a mouse button is released above the view. You can overload this member if your view need to know about mouse-up events or if your view support drag and drop. If mouse-up was the result of ending a drag and drop operation the pcData member will point to a Message containing the dragged data. Look at BeginDrag() for a more detailed description of the drag and drop system. The default implementation of this member will call MouseDown() on it's parent view if one exists. Parameters: cPosition   Mouse position in the views coordinate system at the time the mouse was pressed. nButtons   Index of the pressed button. Buttons start at 1 for the left button, 2 for the right button, 3 for the middle button. Additional buttons might be supported by the mouse driver and will then be assigned numbers from 4 and up. pcData   Pointer to a Message object containing the dragged data if this mouse-up was the end of a drag and drop operation. If no data was dragged it will be NULL. See also: MouseDown(), MouseMove(), WheelMoved() Author: Kurt Skauen ([email protected]) Reimplemented from os::View.

void CheckBox::Paint (  const Rect & cUpdateRect )  [virtual]

Description: Note: Warning: Parameters: cUpdateRect   A rectangle enclosing all damaged areas. This is just a rough "worst-case", further fine-grained clipping will be performed by the Application Server to avoid updating non-damaged pixels and make the update as fast and flicker-free as possible. See also: Invalidate(), Flush() Author: Kurt Skauen ([email protected]) Reimplemented from os::View.

void CheckBox::PostValueChange (  const Variant & cNewValue )  [virtual]

Reimplemented from os::Control.
