GetViewportSize

GetViewportSize

The GetViewportSize function returns the width and height of the interior of the main Mira window.

Syntax

w, h = GetViewportSize()

w and h are the width and height of the Mira window, measured in screen pixels.

Example

The script fragment below shows how to create a text output window having a specified width and height. The CreateTextWindowfunction accepts relative dimensions rather than absolute ones. For example, it takes a Window rectangle like (0.1, 0.7, 0.1, 0.6) relative to the size of the main Mira window. To create a Text Editor window that is 600 pixels wide x 400 pixels tall, anchored at the upper left corner, we would do the following:

function MakeTextWnd(sTitle,w,h)	-- make a function to do this
local wMira,hMira = GetViewportSize()	-- maximum width and height
local R = CRect:new()	-- create a CRect object
R:Set(0,w/wMira,0,h/hMira)	-- scale to the viewport
local W = CreateTextWindow(sTitle,R)	-- format the string
R:delete()	-- no longer needed.
return W	-- return the window reference
end

T = MakeTextWnd("My Title",600,400)	-- is returned the window pointer T
