Parent Window

Mostly component class based objects (currently: ctext and cpicture) supports parameters for parent object (parent window) on initialization.

Advantages:

• all positions are relativ to parent window body, in which 'body' is the area below lower edge of header and upper edge of footer, means: x=0 left within body, y = 0 top within body.
• paint() / hide() are not absolutely necessary, it's enough to paint or hide the parent window
• also a window itself can be a child object
• it's possible to interleave objects

Example:

local n = neutrino() local x = 200 local y = 120 local dx = 910 local dy = 480 local vSpace = 40 local xStart = 10 local yStart = 20 -- parent Window local w = cwindow.new{x=x, y=y, dx=dx, dy=dy, title="Lua Neutrino-API: parent window", icon="info", btnRed="Ende"} -- cpicture item cpicture.new{parent=w, x=xStart, y=yStart , dx=40, dy=40, image="rot"} cpicture.new{parent=w, x=xStart, y=yStart+vSpace*1, dx=40, dy=40, image="gruen"} cpicture.new{parent=w, x=xStart, y=yStart+vSpace*2, dx=40, dy=40, image="gelb"} cpicture.new{parent=w, x=xStart, y=yStart+vSpace*3, dx=40, dy=40, image="blau"} cpicture.new{parent=w, x=xStart, y=yStart+vSpace*4, dx=40, dy=40, image="info"} cpicture.new{parent=w, x=xStart, y=yStart+vSpace*5, dx=40, dy=40, image="help"} -- ctext item ctext.new{parent=w, x=xStart+60, y=yStart , dx=dx-80, dy=40, text="Dieses ist der rote Knopp.", font_text=FONT['MENU']} ctext.new{parent=w, x=xStart+60, y=yStart+vSpace*1, dx=dx-80, dy=40, text="2. Zeile...", font_text=FONT['MENU']} ctext.new{parent=w, x=xStart+60, y=yStart+vSpace*2, dx=dx-80, dy=40, text="usw. ...", font_text=FONT['MENU']} ctext.new{parent=w, x=xStart+60, y=yStart+vSpace*3, dx=dx-80, dy=40, text="usw. ...", font_text=FONT['MENU']} ctext.new{parent=w, x=xStart+60, y=yStart+vSpace*4, dx=dx-80, dy=40, text="usw. ...", font_text=FONT['MENU']} ctext.new{parent=w, x=xStart+60, y=yStart+vSpace*5, dx=dx-80, dy=40, text="usw. ...", font_text=FONT['MENU']} -- paint window and all items at once w:paint() repeat msg, data = n:GetInput(500) until msg == RC['home'] or msg == RC['red'] w:hide()
