public WidgetC

GUIViewC

RawCanvasC()

Default constructor.
Creates an invalid handle.

RawCanvasC(int sx,int sy)

Constructor.

GdkDrawable * DrawArea()

Access draw area.

void Destroy()

See body class for details.

GtkWidget * Widget()

Access widget.

StringC WidgetName() const

Get widget's name.
Call only from GUI thread.

StringC Name() const

Get name of widget.
Defaults to WidgetName(), but may be differnt for Lables etc.

int WidgetID() const

Get widget id.

bool Create()

Create the widget.

bool GUIShow()

Show widget on the display.
Call only from GUI thread.

bool GUIHide()

Hide widget on the display.
Call only from GUI thread.

bool Show()

Show widget on the display.
Thread safe.

bool Hide()

Hide widget on the display.
Thread safe.

Index2dC Position() const

Widget position.

Index2dC Size() const

Size of wiget in pixels

bool GUISetUSize(IntT x,IntT y)

Set size of widget.
GUI thread only.

void SetState(GtkStateType state)

Set state
One of: GTK_STATE_NORMAL GTK_STATE_ACTIVE GTK_STATE_PRELIGHT, GTK_STATE_SELECTED GTK_STATE_INSENSITIVE

IndexRange2dC Rectangle() const

Widget position and extent within its parent window.

DListC<WidgetC> operator +(const WidgetC & widge) const

Add a widget into a list.

Signal0C & Signal(const char * nm)

Get handle for named signal.
Signal is created and connected when this function is first called. There after the same signal is returned.

If the signal is unrecognised an invalid handle is returned.

The exact signal type depends on the signal requested, if not otherwise specified it is a Signal1C.

void SetToolTip(const char * text,const char * ctxt = 0)

Set the tool tip for the widget.
NB. Not all widgets can display tooltips.

void AddEventMask(IntT event)

Add to the event mask.

void DelEventMask(IntT event)

Remove from the event mask.

void ShapeCombineMask(GdkBitmap * mask,int off_x = 0,int off_y = 0)

Make a shape mask for the widget.
GUI thread only.

void GUIGrabFocus()

Grab keyboard focus.

bool GUIDNDSource(ModifierTypeT flags,const SArray1dC<GtkTargetEntry> & entries,DragActionT actions)

Setup widget as drag and drop source.
e.g. GDK_BUTTON1_MASK GDK_BUTTON2_MASK or GDK_BUTTON3_MASK

bool GUIDNDSourceDisable()

Disable widget as a drag and drop source.

bool GUIDNDTarget(DestDefaultsT flags,const SArray1dC<GtkTargetEntry> & entries,DragActionT actions)

Setup widget as drag and drop target.

bool GUIDNDTargetDisable()

Disable widget as a drag and drop source.

const RCHandleC<WidgetBodyC> & operator =(const RCHandleC<WidgetBodyC> & oth)

Assign handle.

RCHandleC<WidgetBodyC> DeepCopy(UIntT levels = ((UIntT))) const

Do a deep copy of the object.

bool operator ==(const RCHandleC<WidgetBodyC> & oth) const

Are handles to the same object ?

bool operator !=(const RCHandleC<WidgetBodyC> & oth) const

Are handles to different objects ?

UIntT Hash() const

Default hash function.
This hashes on the address of the body.

bool IsValid() const

Test if this is a valid handle.

void Invalidate()

Invalidate this handle.
Unattaches the body from the handle.

bool IsHandleType(const DT &) const

Is handle of given type ?

void CheckHandleType(const DT & dummy) const

Check handle type. Throw an expception if not.

UIntT References() const

Find the number of references to the body of this object.

ostream & operator <<(ostream & strm,const RCHandleC<WidgetBodyC> & obj)

istream & operator >>(istream & strm,RCHandleC<WidgetBodyC> & obj)
