Description
If you change the position (left) of parent View the child views will start shrinking. I have been told to use //$.container.width=Ti.Platform.displayCaps.platformWidth;
However, Ti.Platform.displayCaps.platformWidth gives me 320 on retina display. I need 640 for this to work. I am using everything in pixels as I defined in tiapp.xml
Why cannot platformWidth give me 640 which is the true width in pixels? Is it a bug?
platformWidth/Height returns the display units. Here's how to convert those to pixels:
function DPUnitsToPixels(TheDPUnits) { return (TheDPUnits * (Titanium.Platform.displayCaps.dpi / 160)); } // If platformWidth is 320, it converts it to 640 DPUnitsToPixels(Titanium.Platform.DisplayCaps.platformWidth);
