Member Function Documentation

bool guit::GItems::onAdd ( Gadget g)
overridevirtual

Called when the property is added to an object.

note: must call addModes().

Reimplemented from guit::GProp.

virtual GProp* guit::GProp::clone ( bool  copy_value) const
inlinevirtualinherited

Clones the prop (when applicable).

Mutable props (i.e. deriving from GVarProp) can be cloned, otherwise this method returns null. The value is copied if copy_value is used, the default value is used otherwise.

Reimplemented in guit::GTextData, guit::GTip, guit::GBackground, guit::GRelativePos, guit::GCond, guit::GRegText, guit::GDragPos, guit::GDragSize, guit::GExpr, guit::GBorder, guit::GCheck, guit::GColor, guit::GFont, guit::GFlex, guit::GPos, guit::GSize, guit::GFlow, guit::GIcon, guit::GState, guit::GMargin, guit::GShow, guit::GFormat, guit::GCursor, guit::GGap, guit::GAnim, guit::GChoice, guit::GBool, guit::GFloat, guit::GInt, guit::GText, guit::GEnable, and guit::GHotkey.

virtual bool guit::GProp::isMutable ( ) const
inlinevirtualinherited

Returns true if the prop is mutable.

Returns true only if the prop derives from GVarProp and setImmutable() was not called. Props with another type than GVarProp are always immutable.

Reimplemented in guit::GVarProp.

virtual void guit::GProp::setImmutable ( )
inlinevirtualinherited

Makes the prop immutable.

Affects only GVarProp props (other props are always immutable). A prop cannot be made mutable again after this method has been called.

Reimplemented in guit::GVarProp.

virtual GString guit::GProp::stringValue ( ) const
inlinevirtualinherited
virtual float guit::GProp::floatValue ( ) const
inlinevirtualinherited

Returns the value of the prop as a float.

Returns 0.f if the prop has no value of its value cannot be converted to a float.

Reimplemented in guit::GNumExpr, guit::GTextExpr, guit::GBoolExpr, guit::GExpr, guit::GState, guit::GText, and guit::GBool.

virtual bool guit::GProp::boolValue ( ) const
inlinevirtualinherited

Returns the value as a bool.

Returns false if the prop has no value of its value cannot be converted to a bool.

Reimplemented in guit::GNumExpr, guit::GTextExpr, guit::GBoolExpr, guit::GExpr, and guit::GBool.

bool guit::GProp::isEquivalent ( GProp const &  other) const
virtualinherited

Returns true if these props are equivalent.

Adding a prop to a gadget replaces the equivalent prop it contains (if it contains any). In all other cases, the prop is added to the gadget proplist. NOTE: props with a negative role are never equivalent!

Reimplemented in guit::GExpr, guit::GCond, guit::GState, and guit::GAnim.

void guit::GProp::onRemove ( Gadget g)
virtualinherited

Called when the property is removed from an object.

note: must call removeModes().

Reimplemented in guit::GTextData, guit::GTip, guit::GCond, guit::GDragPos, guit::GDragSize, guit::GPos, guit::GText, guit::GSize, guit::GFlex, and guit::GHotkey.

void guit::GObject::error ( GString const &  funname,
GString const &  message 
) const
virtualinherited

Prints an error message.

See Also
GApp::onError() to change error management.
void guit::GObject::ignoreSmartPointers ( )
inlineinherited

Checks/sets whether this object can be auto-deleted by smart pointers.

ignoreSmartPointers() has a permanent effect, contrary to forgetSmartPointers(). Objects not created by calling new are never auto-deleted by smart pointers.

void guit::GObject::forgetSmartPointers ( )
inlineinherited

Forgets all smart pointers pointing this object.

The smart pointers that are currently pointing to the object won't auto-delete it. forgetSmartPointers() has a temporary effect, contrary to ignoreSmartPointers().
