问题 Looking at the new Delphi XE2 with Firemonkey. Considering that it compiles for Windows, Mac OSX and iOS, VCL components are useless in a FireMonkey application. My question is: Is there/will there be an Indy Firemonkey Edition? Cause I seriously need the IdHTTP.Post(); . If not, is there a way to do this in FireMonkey? I have been googling for quite awhile now, not finding anything. :S 回答1: VCL means Visual Component Library . There's nothing about Indy that is "visual" (meaning "seen at

问题 I previously asked this question in the Delphi XE2 timeframe, and the answer then was a pretty ugly hack. Now Delphi XE3 supports non-client theming, according to the official release notes. How do you do it in Delphi XE3 in Firemonkey FM2? I believe it must be something to do with the style-book, but I can't figure it out. The form itself has an "EnableBorderStyling" property which I set to true, and I am thinking I must have to load a style that contains some nonclient theme data, but I can

问题 I need to open a webpage with safari in my iOS application. With XE2 there was iphoneall unit, which exposed UIApplication. XE4 doesn't use FPC anymore, so I can't use that. Embarcadero documentation says I can use SDKs only with C++ or using delphi interfaces (and still, macapi is for OSX only, not iOS). So, it seems that there is no interface for UIKit framework?! Another solution I tried was: _system('open http://www.google.com'); But that had no affect at all! Is there any other ways to

问题 How do you get the currently logged in username in a Firemonkey Delphi project? I'm targeting both Windows and Mac. I have XE2, but I suppose any version solution is fine because I will upgrade if needed. 回答1: For Windows you can use the GetUserName WinAPi function, for OSX you can use the NSUserName and/or NSFullUserName methods. Try this sample for OSX {$APPTYPE CONSOLE} {$R *.res} uses Macapi.CoreFoundation, Macapi.Foundation, System.SysUtils; function NSUserName: Pointer; cdecl; external

问题 How can I save a file locally on an Android device, using Delphi (XE5, Firemonkey)? Something as simple as Memo.Lines.SaveToFile('test.txt') does not seem to work. It results in the following error message: "Cannot create file "/test.txt". Not a directory." 回答1: According to the document Creating an Android App, get the documents path like this: System.IOUtils.TPath.GetDocumentsPath + System.SysUtils.PathDelim + 'myfile'; 回答2: Instead of using System.SysUtils.PathDelim , you may use System

问题 I'm having problems with the navigation between the forms. I have created an Android Firemonkey Mobile Application using Delphi XE5. I currently have a Login Form and the Main Form, now I want advice on how to handle the Login Form to appear before the Main Form. 回答1: In the Project Options, under forms, select the LogonForm to be auto-created, and move all other forms out of the list. Now when you start your application, the Logon form will show as the first (and only) form. Once logged on,
