Buttongadget replacement

Posted: Thu Jun 23, 2011 7:02 am

Hi.
I had the need for a basic buttongadget, but that could include a icon, a text (and multiline if needed) and be multiplatform.
So I made one.

Code: Select all

;init
Enumeration
  #constant_1
  #constant_2
EndEnumeration
Enumeration
  #font
EndEnumeration
LoadFont(#font,"Arial",12)
UsePNGImageDecoder()
;procedures
Procedure WrapText(x,y,text.s,width,color) 
  If TextWidth(text)<=width 
    Debug "TEXTWRAP:"+text+Str(x)+","+Str(y)
    DrawText((width/2)-(TextWidth(text.s)/2),y,text.s,RGBA($4F,$8C,$A3,255)) 
  Else 
    limit=0 : Repeat : limit+1 : Until TextWidth(Left(text,limit))>width : cut=limit 
    Repeat : cut-1 : Until Mid(text,cut,1)=" " Or Mid(text,cut,1)="-" Or cut=0 
    If cut=0 : cut=limit-1 : EndIf 
    DrawText((width/2)-(TextWidth(Left(text,cut))/2),y,Left(text,cut),RGBA($4F,$8C,$A3,255)) 
    wraptext(x,y+16,Right(text,Len(text)-cut),width,color) 
  EndIf 
EndProcedure 
Procedure.l createicon(icon.l,text.s, width=240,height=40,wrap.b=0)
  iconcount.l+1
  image.l=CreateImage(iconcount.l,width,height,32 | #PB_Image_Transparent)
  If icon.l
    image2.l=CatchImage(#constant_1,icon.l)
  Else
    image2.l=CreateImage(#constant_1,24,24)
  EndIf
  StartDrawing(ImageOutput(iconcount.l))
  If icon.l
    DrawAlphaImage(ImageID(#constant_1),10,(height/2)-(ImageHeight(#constant_1)/2),250) ;-(ImageHeight(ImageID(image2.l))/2),250)
  Else
    DrawingMode(#PB_2DDrawing_Default)
    LineXY(1,1,width-1,1,RGB(128,128,196))
    LineXY(1,1,1,height-1,RGB(128,128,196))

  If wrap.b
    wraptext(20,30,text.s,width,RGBA($4F,$8C,$A3,255))    
  Else        
    DrawText((width/2)-(TextWidth(text.s)/2),(height/2)-(TextHeight(text.s)/2),text.s,RGBA($4F,$8C,$A3,255))
  EndIf

  StopDrawing()

:D thx

but you should use Integer for handle and mempointer and your code run on x64! :wink:
icon.l = icon.i
image.l = image.l
...

As I have never conflicts with image and gadget numbers (I put them both into a single enumeration list), I use the following for creating buttons with icons.
The main problem still present is, that I found no simple way to draw strings with underlining instead of showing the '&' prefix (it seems, that DrawText uses the #SS_NOPREFIX flag)...

Code: Select all

Global OptIconsActive=#True

#ButtonIconBorder=10
#ButtonIconPadding=10

Enumeration
	#ButtonIcon_Left
	#ButtonIcon_Center
EndEnumeration

#NoTransparency=$ff000000
#FullTransparency=$00000000

Procedure SetGadgetIconText(Gadget,IconHandle,Text.s,IconSize=16,IconPosition=#ButtonIcon_Left)

	Protected Font=GetGadgetFont(#PB_Default)
	Protected BW,BH,IW
	Protected W_,T_

	BW=GadgetWidth(Gadget)
	BH=GadgetHeight(Gadget)
	IW=IconSize+#ButtonIconPadding
	
	CreateImage(Gadget,1,1)
	StartDrawing(ImageOutput(Gadget))
	DrawingFont(Font)
	W_=IW+TextWidth(Text)
	T_=(BH-TextHeight("Wg"))>>1
	StopDrawing()

	Select IconPosition
	Case #ButtonIcon_Left
		W_=#ButtonIconBorder
	Case #ButtonIcon_Center
		W_=(BW-W_)>>1
	EndSelect

	CreateImage(Gadget,BW,BH,32)
	StartDrawing(ImageOutput(Gadget))

	DrawingMode(#PB_2DDrawing_AlphaChannel)
	Box(0,0,BW,BH,#FullTransparency)

	DrawingMode(#PB_2DDrawing_AlphaBlend|#PB_2DDrawing_Transparent)
	DrawingFont(Font)
	;Box(0,0,16,16,#NoTransparency|#Red)
	DrawText(W_+IW,T_,Text,#NoTransparency|#Black)
	If IconHandle
		DrawImage(IconHandle,W_,(BH-IconSize)>>1)
	EndIf
	StopDrawing()

	SetGadgetAttribute(Gadget,#PB_Button_Image,ImageID(Gadget))

EndProcedure
Procedure GadgetIconText(Gadget,X,Y,W,H,IconHandle,Text.s,Flags=0)
	
	If OptIconsActive
		ButtonImageGadget(Gadget,X,Y,W,H,0)
		SetGadgetIconText(Gadget,IconHandle,ReplaceString(Text,"&",""),24)
	Else
		ButtonGadget(Gadget,X,Y,W,H,Text)
	EndIf
	
EndProcedure


OpenWindow(0, 0, 0, 512, 384, "", #PB_Window_ScreenCentered | #PB_Window_SystemMenu | #PB_Window_SizeGadget | #PB_Window_MinimizeGadget | #PB_Window_MaximizeGadget)
