问题 Does anyone know how to turn off the anti-aliasing in TChart for Firemonkey in Delphi XE2? 回答1: FireMonkey Canvas does not allow enabling or disabling anti-alias for individual controls.

问题 I have an (Delphi XE2) VCL app containing an object TDownloadUrl (VCL.ExtActns) to check several webpages, so I wonder if there is an equivalent object in FireMonkey, 'cause I wanna take advantage of rich features from this new platform.

问题 I am looking at the FMX built in logging support via the Log class which uses the IFMXLoggingService to write events. I have found info for the log file location in iOS and Android but unable to find anything on Windows (8.1).

When i work on a device that have a normal resolution of 1 (scene.scale=1) then component like TRoundRect, TPie, etc produce ugly result because they are not anti-aliased (or the anti-alias is not visible by humain eyes). if i work on high definition device (scene.scale=2 for exemple), then it's not really a big problem because high definition compensate the problem. So first question, is their any way to make theses component

问题 I have a THorzScrollBox in a form, and some TStyledControls inside. Each StyledControl has a Tag to identify. Using an TEdit to inform a value, I can find inside the ScrollBox an specific Control by his tag . If the control that I searched is not on the screen, I want to scroll the ScrollBox to show it.
