Detailed Description

Functions that deal with scaling objects.

Edje allows one to build scalable interfaces. Scaling factors, which are set to neutral (1.0) values by default (no scaling, actual sizes), are of two types: global and individual.

Scaling affects the values of minimum/maximum part sizes, which are multiplied by it. Font sizes are scaled, too.

Function Documentation

void edje_scale_set ( double  scale)

Set Edje's global scaling factor.

Parameters
scaleThe global scaling factor (the default value is 1.0)

Edje's global scaling factor will affect all its objects which hadn't their individual scaling factors altered from the default value (which is zero). If they had it set differently, by edje_object_scale_set(), that factor will override the global one.

Warning
Only parts which, at EDC level, had the "scale" property set to 1, will be affected by this function. Check the complete syntax reference for EDC files.

double edje_scale_get ( void  )

Retrieve Edje's global scaling factor.

Returns
The global scaling factor

This function returns Edje's global scaling factor.

Examples:

Eina_Bool edje_object_scale_set ( Evas_Object obj,
double  scale 
)

Set the scaling factor for a given Edje object.

Parameters
objA handle to an Edje object
scaleThe scaling factor (the default value is 0.0, meaning individual scaling not set)

This function sets an individual scaling factor on the obj Edje object. This property (or Edje's global scaling factor, when applicable), will affect this object's part sizes. If scale is not zero, than the individual scaling will override any global scaling set, for the object obj's parts. Put it back to zero to get the effects of the global scaling again.

Warning
Only parts which, at EDC level, had the "scale" property set to 1, will be affected by this function. Check the complete syntax reference for EDC files.

double edje_object_scale_get ( const Evas_Object obj)

Get a given Edje object's scaling factor.

Parameters
objA handle to an Edje object

This function returns the individual scaling factor set on the obj Edje object.
