Determining the width of rendered text
User Question :
I have a set of controls arranged horizontally and the width of the control is proportional to the width of the rendered text. This will cause a problem when translations are applied. Is there a way of determining the width of the rendered text so that the controls can be dynamically resized?
I've attached a Lua module (measure.lua) that you can try using. You could do something like:
local data = gre.get_control_attrs(CONTROL_NAME, "width", "height")
local metrics = Measure.create(FONT, FONT_SIZE, WRAP, TEXT)
print("Max Width: " .. metrics:getMaxWidth())
CONTROL_NAME is the path to your control holding your text,
FONT is the name of your font, eg. "fonts/Roboto-Bold.ttf",
FONT_SIZE if a number,
WRAP is a boolean whether the text is wrapped or not,
and TEXT is the actual body of your text you are using in your control.
Hope this helps.
