UI control hierarchy

[dexterpost]

Dear All,

We are new to python, as observed in series 60 we can create hierarchy of controls using container controls. How do i create container control and add child controls to it in Python for Series 60? If that is not possible is there another option. Appreciate your support.


Regards,
Dexter.

I had already answered you before.

Do you know we can have sublists too. Selection lists!

hi dexterpost
i am not getting your exact problem. but i am attaching one code. hope you will find your answer. this is application for GUI learning.

import appuifw, e32, key_codes, graphics

RED = (255,0,0) #tuple
BLUE = (0,0,255) #tuple
GRAY = (150, 150, 150)
RectCord = [50,100,80,140]
RountPoint = [125,125]
Direction = u"None"
shap = u"None"
def DrawRound():
	shap = u"Round"
	img.clear(GRAY)
	img.point((125,125), outline = BLUE, width = 30)
	handle_redraw(None)

def DrewRect():
	shap = u"Rect"
	img.clear(GRAY)
	img.rectangle((50,100,80,140), fill = RED)
	handle_redraw(None)

def MoveRect(Direction):	
	# put negetive check later
	img.clear(GRAY)
	if Direction == u"Left":
		img.rectangle((50-10,100,80-10,140),fill = RED)
	elif Direction == u"Right":
		img.rectangle((50+10,100,80+10,140),fill = RED)
	elif Direction == u"Up":
		img.rectangle((50,100-10,80,140-10),fill = RED)
	elif Direction == u"Down":
		img.rectangle((50,100+10,80,140+10),fill = RED)


def MoveRound (Direction):
	# put negetive check later	
	img.clear(GRAY)
	if Direction == u"Left":
		img.point((125-10,125),outline = BLUE, width = 30)
	elif Direction == u"Right":
		img.point((125+10,125),outline = BLUE, width = 30)
	elif Direction == u"Up":
		img.point((125,125-10),outline = BLUE, width = 30)
	elif Direction == u"Down":
		img.point((125,125+10),outline = BLUE, width = 30)



def handle_redraw(rect):	
	if img:
		canvas.blit(img)

def handle_event(event):
	if event['keycode'] == key_codes.EKeyLeftArrow:
		Direction = u"Left"
		if shap.find(u"Round") == 1:
			MoveRound(Direction)
		else:
			MoveRect(Direction)
	elif event['keycode'] == key_codes.EKeyRightArrow:
		Direction = u"Right"
		if shap.find(u"Round") == 1:
			MoveRound(Direction)
		else:
			MoveRect(Direction)
	elif event['keycode'] == key_codes.EKeyUpArrow:
		Direction = u"Up"
		if shap.find(u"Round") == 1:
			MoveRound(Direction)
		else:
			MoveRect(Direction)

	elif event['keycode'] == key_codes.EKeyDownArrow:
		Direction = u"Down"
		if shap.find(u"Round") == 1:
			MoveRound(Direction)
		else:
			MoveRect(Direction)	
		
	handle_redraw(None)		

def quit():
	app_lock.signal()

appuifw.app.title = u"shapMoving"
appuifw.app.menu = [(u"Round",DrawRound),(u"Rectangle",DrewRect)]

img = None
canvas = appuifw.Canvas(redraw_callback = handle_redraw, event_callback = handle_event)
appuifw.app.body = canvas
appuifw.app.screen = "normal"
appuifw.app.exit_key_handler = quit

# Intialise screen with gray
w,h = canvas.size
img = graphics.Image.new((w,h))
img.clear(GRAY)

app_lock = e32.Ao_lock()
app_lock.wait()

here everything is done by appuifw module.
