The Appeon resize object helps developers easily resize UI elements to fit with multiple screens, especially for the mobile apps.
The eon_appeon_resize object provides the most capacity and flexibility because it can not only resize the window and the user object container, but also the controls and the font, at the same time, it also allows you to dynamically change the resize behavior for a particular window/user object/control at runtime.

Syntax
of_fontresize ( boolean
ab_resize, integer

automatically resized; when false, the font is not
resized.
ai_type - 1 - Resizes with the
height; 2 - Resizes with the width; 3 - Resizes with the height
or width whichever has the smaller change in proportion; 4 -

Description
Gets the original tag of a control or object. Original tag includes the information that is not altered by the of_init function.
Syntax
of_gettag ( windowobject
awo )
Parameter
awo - The name of the object or
control.
Return value
String. The original tag information of the control or object.
Description
Initializes the user object container or the window that
needs to be resized. You can initialize the user object
container or the window only; you can also initialize the
controls contained in the user object container or the window by
setting the ab_recursion parameter to
true. Only the initialized user object/window/control can be
resized, therefore, this function must be the very first one to
be called.
By initializing the user object/window/control, it actually registers the following information to the Tag property of the user object/window/control, separated by "/":
register flag/resize
flag/flag/x
ratio/y
ratio/width
ratio/height
ratio/width/height/x/y/parentwidth/parentheight/{textsize}/original
tag
flag: used by the developer to
manually specify the resize behavior of a control or object,
such as scaletobottom, fixtoright etc. By default, the value is
"1111". It can be set by using the of_setflag function.
textsize: only effective when the
control or object has the textsize property.
Syntax 1: Initializes the user object.
If ab_recursion is true, all of the
controls contained in the user object will be initialized as
well.
of_init ( userobject
au_uo, boolean
ab_recursion )
Syntax 2: Initializes the user object.
If ab_recursion is true, all of the
controls contained in the user object will be initialized as
well.
of_init ( userobject
au_uo, integer
ai_width, integer
ai_height, boolean
ab_recursion )
Syntax 3: Initializes the window and the
controls in it. If ab_recursion is
true, all of the user objects and tab controls contained in
the window will be initialized as well.
of_init ( window
aw_window, boolean
ab_recursion )
Parameter
au_uo - The name of the user object
container to be initialized.
aw_window - The name of the window
container to be initialized, and the controls in the window will
be automatically initialized as well.
ai_width - The new width of the
user object container. The original proportion of each control
will be calculated based on it.
ai_height - The new height of the
user object container. The original proportion of each control
will be calculated based on it.
ab_recursion - When true, the
controls contained in the user object container will be
initialized as well; or the user objects and tab controls in the
window container will be initialized as well; when false, only
the user object container or the window (and controls in the
window) will be initialized.
Return value
None
Description
Changes the ratio of a single object or control that has been registered using of_init.
Syntax
of_init_object ( windowobject
awo, decimal
ad_xscale, decimal
ad_yscale, decimal

of_init_object ( windowobject
awo, integer
ai_parentwidth, integer
ai_parentheight, boolean
ab_recursion )
of_init_object ( windowobject
awo, boolean
ab_recursion )
Comparatively speaking, the second syntax is easier to use and produce the desired layout; the first syntax would require more testing to determine an accurate x/y ratio.
The third syntax is for refreshing the object or control easily without needing a lot arguments.
Parameter
awo - The name of the object or
control to be initialized.
ad_xscale - The new x ratio.
ad_yscale - The new y ratio.
ad_wscale - The new width
ratio.
ad_hscale - The new height
ratio.
ai_parentwidth - The new width of
the parent container.
ai_parentheight - The new height of
the parent container.
ab_recursion - When true, the
controls contained in the object or the control will be
initialized as well; when false, only the object or the control
will be initialized.
Return value
None
