Title: Programming in Symbian OS
| Old | New | Line | |
|---|---|---|---|
| 1 | + | This page is a tutorial about how one can use the Symbian OS API to write software | |
| 2 | + | ||
| 3 | + | ## Overview | |
| 4 | + | ||
| 5 | + | ### Hello World | |
| 6 | + | ||
| 7 | + | **Description** | |
| 8 | + | ||
| 9 | + | When started, this software will display a 'My Pascal Hello' message on the screen and then quit. The message will remain for about 5 seconds. | |
| 10 | + | ||
| 11 | + | **Notes** | |
| 12 | + | ||
| 13 | + | - User_InfoPrint will return a integer with a error message, but we just ignore it on this hello world | |
| 14 | + | - We are using the procedural bindings, througth the symbian.pas unit, and not the object-oriented bindings | |
| 15 | + | ||
| 16 | + | **Code** | |
| 17 | + | ||
| 18 | + | QPasHello.ini | |
| 19 | + | ||
| 20 | + | ``` ini | |
| 21 | + | [Main] | |
| 22 | + | EXENAME=QPasHello.exe | |
| 23 | + | TARGETTYPE=EXE | |
| 24 | + | UID2=0x100039CE | |
| 25 | + | UID3=0xE1000002 | |
| 26 | + | ||
| 27 | + | [Files] | |
| 28 | + | source0=QPasHello.pas | |
| 29 | + | ``` | |
| 30 | + | ||
| 31 | + | QPasHello.pas | |
| 32 | + | ||
| 33 | + | ``` pascal | |
| 34 | + | program qpashello; | |
| 35 | + | ||
| 36 | + | {$mode objfpc}{$H+} | |
| 37 | + | ||
| 38 | + | uses symbian; | |
| 39 | + | ||
| 40 | + | var | |
| 41 | + | aMsg: array[0..255] of Char; | |
| 42 | + | begin | |
| 43 | + | aMsg := 'My Pascal Hello'; | |
| 44 | + | User_InfoPrint(aMsg); | |
| 45 | + | end. | |
| 46 | + | ``` | |
