Margins of a gadget.
|
explicit |
Constr.
argument can contain 2 or 4 floats separated by spaces, i.e.:
|
overridevirtual |
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 from guit::GProp.
|
inlineoverridevirtualinherited |
|
inlinevirtualinherited |
Changes the value.
Callbacks are fired and parent gadgets updated if:
|
inlineoverridevirtualinherited |
Changes value.
Does nothing if the type of from is not convertible to the type of this prop.
Implements guit::GVarProp.
|
inlineoverridevirtualinherited |
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 from guit::GProp.
|
inlineoverridevirtualinherited |
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 from guit::GProp.
|
virtualinherited |
Changes value by blending the value of two props.
Does nothing if the type of from1 or from2 is not convertible to the type of this prop.
Reimplemented in guit::GColor, guit::GPos, and guit::GSize.
|
inherited |
Unbinds this prop.
Importantly, these methods unbinds props both ways if the binding was done both ways (e.g. by using sync())
|
inherited |
Blinks gadget parents of the prop.
Shows a warning if msg is not empty.
|
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.
|
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.
|
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.
|
virtualinherited |
Called when the property is added to an object.
note: must call addModes().
Reimplemented in guit::GTextData, guit::GTip, guit::GCond, guit::GDragPos, guit::GDragSize, guit::GPos, guit::GText, guit::GSize, guit::GFlex, guit::GFlow, guit::GItems, and guit::GValue.
|
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.
|
virtualinherited |
Prints an error message.
|
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.
|
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().
