Need tips for SplitterGadget and Gadgets resize

Hi,

I'm playing with SplitterGadget and several gadgets inside. I would like to know if my way of managing the resizing of gadgets is fine.

Code: Select all

Global first_width = 400
Global first_height = 400

Enumeration Gadgets
	#ScrollArea
	#container
	#Splitter
	#listicon
	#panel
	#str1
	#str2
	#str3
	#str4
	#str5
	#status
EndEnumeration

Procedure BindSplitterV()
	Static SplitterPos
	Protected Position = GetGadgetState(EventGadget())
	If SplitterPos <> Position
		SplitterPos = Position

		ResizeGadget(#listicon, #PB_Ignore, #PB_Ignore, GadgetWidth(#container) - 15, #PB_Ignore)
		ResizeGadget(#ScrollArea, #PB_Ignore, #PB_Ignore, GadgetWidth(#panel) - 12, GadgetHeight(#panel) - 30)
		SetGadgetAttribute(#ScrollArea, #PB_ScrollArea_InnerWidth, GadgetWidth(#ScrollArea) - 30)
		SetGadgetAttribute(#ScrollArea, #PB_ScrollArea_InnerHeight, GadgetHeight(#ScrollArea) + 140)

		ResizeGadget(#str1, #PB_Ignore, #PB_Ignore, GadgetWidth(#ScrollArea) - 80, #PB_Ignore)
		ResizeGadget(#str2, #PB_Ignore, #PB_Ignore, GadgetWidth(#ScrollArea) - 80, #PB_Ignore)
		ResizeGadget(#str3, #PB_Ignore, #PB_Ignore, GadgetWidth(#ScrollArea) - 80, #PB_Ignore)
		ResizeGadget(#str4, #PB_Ignore, #PB_Ignore, GadgetWidth(#ScrollArea) - 80, #PB_Ignore)
		ResizeGadget(#str5, #PB_Ignore, #PB_Ignore, GadgetWidth(#ScrollArea) - 80, #PB_Ignore)

		; to remove the flickering
		UpdateWindow_(GadgetID(#listicon))
		UpdateWindow_(GadgetID(#status))
	EndIf
EndProcedure

Procedure ResizeEvent()
	new_width = WindowWidth(0)
	new_height = WindowHeight(0)

	inc_Width = new_width - first_width
	inc_Height = new_height - first_height

	ResizeGadget(#Splitter, #PB_Ignore, #PB_Ignore, 390 + inc_Width, 390 + inc_Height)

	ResizeGadget(#listicon, #PB_Ignore, #PB_Ignore, GadgetWidth(#container) - 15, 200 + inc_Height)
	ResizeGadget(#status, #PB_Ignore, 5 + GadgetHeight(#listicon), #PB_Ignore, #PB_Ignore)

	ResizeGadget(#ScrollArea, #PB_Ignore, #PB_Ignore, GadgetWidth(#panel) - 12, GadgetHeight(#panel) - 30)
	SetGadgetAttribute(#ScrollArea, #PB_ScrollArea_InnerWidth, GadgetWidth(#ScrollArea) - 30)
	SetGadgetAttribute(#ScrollArea, #PB_ScrollArea_InnerHeight, GadgetHeight(#ScrollArea) + 140)

	ResizeGadget(#str1, #PB_Ignore, #PB_Ignore, GadgetWidth(#ScrollArea) - 80, #PB_Ignore)
	ResizeGadget(#str2, #PB_Ignore, #PB_Ignore, GadgetWidth(#ScrollArea) - 80, #PB_Ignore)
	ResizeGadget(#str3, #PB_Ignore, #PB_Ignore, GadgetWidth(#ScrollArea) - 80, #PB_Ignore)
	ResizeGadget(#str4, #PB_Ignore, #PB_Ignore, GadgetWidth(#ScrollArea) - 80, #PB_Ignore)
	ResizeGadget(#str5, #PB_Ignore, #PB_Ignore, GadgetWidth(#ScrollArea) - 80, #PB_Ignore)
