问题 I want to play system sound in both Windows and MAC OS X. To play sound in Windows used something like this: PlaySound('C:\Windows\Media\Windows Default.wav', 0, SND_FILENAME + SND_ASYNC); I am sure I have to use TMediaPlayer. 回答1: You are correct, you can use the TMediaPlayer component, documentation clearly states : TMediaPlayer playbacks audio files and the audio component of a video file.

问题 Does anyone know how to retrieve the column and row when selecting a cell in a FireMonkey stringgrid (in other words, when clicking on a cell, we want to know which column/row is being selected)...?

问题 I have a FireMonkey app with a GridPanelLayout, aligned to client. It's got 6 columns and 16 rows. Controls include glyphs, edits, and buttons. The TEdits span multiple columns, and the TButtons span both multiple columns and rows. The controls are currently all aligned to client. When I compile and run on Windows everything looks and acts as expected. However, on Android devices (I tried two, Android 6.0.1, and Amazon FireOS) none of the controls span more than one column or row. They're

问题 I managed to get Xcode (running as a VM under Windows) pushing an XE2 build FireMonkey iOS HD app to my (jailbroken) iPhone after XE-script-prep (creating the Xcode folder), with a valid company certificate. Anyway, faking the native cocoa controls seems a little seedy, but sticking a TToolbar (panel with standard iPhone gradient), a couple of TSpeedButtons (which have this curious V slope thing going on), and a TStringGrid and you're almost in the realms of basic iPhone app design.

Selection color applies to the selected Row. Changing focus color is a straight forward process: procedure ChangeGridCellFocusColor

问题 I have the following Delphi code for showing a modal message on Android which worked fine on 10.1 Berlin, but stopped working on Delphi 10.2.1 Tokyo. This procedure now hangs the Android app. procedure customShowMessage(AMessage: string); //good idea to have our own procedure that we can tweak, as even for VCL and windows, we have done show message differently over the years due to all sorts of funny problems var LModalWindowOpen: boolean; begin LModalWindowOpen := true; TDialogService

问题 I'm having a problem with NSObject instances being freed when I don't expect. I have a form variable of type NSNumber, in button1 I create an instance and set a value, in button2 I read the value. If I don't call retain in button 1 then the variable is freed and the app hangs when I click button2, adding a call to retain makes everything work. This is on OSX using Delphi XE6 with firemonkey. Here's some code Define a form variable of type NSNumber Fv : NSNumber; Now add a couple of buttons
