Good day developers

Mi pregunta es la siguien te como puedo poner un fondo a un “Widget.newTabBar”

try with the characteristic “backgroundFile” but didn’t work.

– create the actual tabBar widget

tabBar = widget.newTabBar{

top = display.contentHeight - 100, – 50 is default height for tabBar widget

backgroundFile = “tabBarBack.png”, — It did not work

buttons = tabButtons

}

tabBar:setSelected( false )

Look in your console log. Are there any errors or warnings?

If you want to specify a background, you also have to specify the left, center, and right of the foreground of the button as well.

local tabBarBackgroundFile = "images/tabBarBg7.png" local tabBarLeft = "images/tabBar\_tabSelectedLeft7.png" local tabBarMiddle = "images/tabBar\_tabSelectedMiddle7.png" local tabBarRight = "images/tabBar\_tabSelectedRight7.png" local tabBar = widget.newTabBar{ &nbsp;&nbsp;&nbsp; top =&nbsp; display.contentHeight - 50, &nbsp;&nbsp;&nbsp; left = 0, &nbsp;&nbsp;&nbsp; width = display.contentWidth, &nbsp;&nbsp;&nbsp; backgroundFile = tabBarBackgroundFile, &nbsp;&nbsp;&nbsp; tabSelectedLeftFile = tabBarLeft,&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; -- New &nbsp;&nbsp;&nbsp; tabSelectedRightFile = tabBarRight,&nbsp;&nbsp;&nbsp; -- New &nbsp;&nbsp;&nbsp; tabSelectedMiddleFile = tabBarMiddle,&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; -- New &nbsp;&nbsp;&nbsp; tabSelectedFrameWidth = 20,&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; -- New &nbsp;&nbsp;&nbsp; tabSelectedFrameHeight = 50,&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; -- New&nbsp;&nbsp; &nbsp; &nbsp;&nbsp;&nbsp; buttons = tabButtons, &nbsp;&nbsp;&nbsp; height = 50, }
