gre.set control attrs

gre.set_control_attrs(
    control_name,
    tag_table
)
            

Set properties for a control.  The control_name is the name of the control or a variable. The tag_table contains the tags and values for the properties to set.

        x,  y, width, height, hidden, active, zindex, findex, effect, mask_enabled

In the case of the focus index (findex), the initial value set in Storyboard Designer must be non-zero in order for it to be changed dynamically at runtime

The effect tag is a special attribute that can be used with OpenGL rendering platforms to apply a custom shader directly as an effect on the control object

function set_control_hidden()
    local dk_data = {}
    dk_data["hidden"] = 1
    gre.set_control_attrs("my_control", dk_data)       
end
            

function set_control_blur_effect()
    local dk_data = {}
    local effect = {}

    effect["name"] = "blur"
    effect["passes"] = 3
    effect["radius"] = 1
    effect["composite"] = true

    dk_data["effect"] = effect
    gre.set_control_attrs("my_control", dk_data)
end
