Hello, I've been told to do something I'm planning on doing I need to drop a TApplication object on my form. I'm pulling my hair out trying to find out where this component is. What toolbar is TApplication on? What does its icon look like? Thanks! Back to top Maarten Wiltink Guest Posted: Thu Sep 29, 2005 5:57 pm    Post subject: Re: Where is TApplication located?

The Forms unit creates a TApplication object in its initialisation section. It represents the entirety of your program, tt's not something you drop on a form. There _is_ a TApplicationEvents in (later versions of) Delphi, and that is something you drop on a form. In Delphi 5, it's on the Additional tab and looks like the little torch on a blue globe that is (was?) the default icon for applications, with arrows pointing away from it. So, considering that apparently what you were told (or perhaps your recollection of it) wasn't overly accurate, what were you planning on doing?

Use the routine given, but make it a method of your form: procedure TForm1.OnMessage (var Msg: TMsg; var Handled: Boolean) ; var i: SmallInt; begin if Msg.message = WM_MOUSEWHEEL then begin Msg.message := WM_KEYDOWN; Msg.lParam := 0; i := HiWord(Msg.wParam) ; if i > 0 then Msg.wParam := VK_UP else Msg.wParam := VK_DOWN; Handled := False; end; end; Then in your form's oncreate: application.onmessage:=onmessage; Cheers, Nicholas Sherlock Back to top Maarten Wiltink Guest Posted: Fri Sep 30, 2005 8:20 am    Post subject: Re: Where is TApplication located?

His name seems to come up rather often there. Quote: Use the routine given, but make it a method of your form: <snip code> Quote: Then in your form's oncreate: application.onmessage:=onmessage; Some people thrive on programming by clicking alone, and would benefit (in a short term sense) from using a TApplicationEvents component to put this in its place. Zarko arguably made a speeling mistake, but I wouldn't class him as "weird" for that. As for catering to doubleclick-dummies...

Ah, wasn't aware of this component (Never used it before). Forget my comment, then .

Use the routine given, but make it a method of your form: I would also suggest correcting the if satement condition to also check if the Msg.Hwnd belongs to a TDBGrid descendant. Also, one wheel message by defaut transcribes to 3 key messages, right? It should be possible to get this value. -- I'm not having these two shag while I'm tied to a chair three feet away.

Try this function GetScrollLines: integer; begin if not SystemParametersInfo (spi_GetWheelScrollLines, 0, @Result, 0) then Result := 3; end; My copy of Win32.hlp says BOOL SystemParametersInfo( UINT uiAction, // system parameter to query or set UINT uiParam, // depends on action to be taken PVOID pvParam, // depends on action to be taken UINT fWinIni // user profile update flag ); <snip> SPI_SETWHEELSCROLLLINES Windows NT only: Sets the number of lines to scroll when the mouse wheel is rotated. The number of lines is set from the uiParam parameter. -- Henry Bartlett Delphi Links Page: ( http://www.hotkey.net.au/~hambar/habit/delflink.htm ) Back to top Display posts from previous: All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First         BorlandTalk.com Forum Index -> comp.lang.pascal.delphi.misc All times are GMT Page 1 of 1   Jump to: Select a forum C++ Builder Newsgroups----------------C++ BuilderC++ Builder (ActiveX)C++ Builder (Announcements)C++ Builder (Command Line Tools)C++ Builder DatabasesC++ Builder Databases (ADO)C++ Builder Databases (Desktop)C++ Builder Databases (InterBase Express)C++ Builder Databases (Multi-Tier)C++ Builder Databases (SQL Servers)C++ Builder (Graphics)C++ Builder (IDE)C++ Builder (Internet)C++ Builder (Internet Socket)C++ Builder (Internet Web)C++ Builder (Jobs)C++ Builder (Language)C++ Builder (Language C++)C++ Builder (Compatibility with MFC)C++ Builder (Native API)C++ Builder (Non-Technical)C++ Builder (Students)C++ Builder (Third Party Tools)C++ Builder (Upgrade)C++ Builder (VCL)C++ Builder (VCL Components Usage)C++ Builder (VCL Components Development)C++ Builder (VCL Usage)C++ Builder (WinAPI)C++ Builder Installation Delphi Newsgroups----------------Delphi (General)Delphi ActiveX Controls UsageDelphi ActiveX Controls DevelopmentDelphi As400Delphi DatabasesDelphi Databases (ADO)Delphi Databases (dbExpress)Delphi Databases (Desktop)Delphi Databases (InterBase Express)Delphi Databases (Multi-Tier)Delphi Databases (SQL Servers)Delphi DeploymentDelphi GraphicsDelphi IDEDelphi InternationalizationDelphi InternetDelphi Internet Isapi-WebBrokerDelphi Internet WebSnapDelphi Internet WinsockDelphi JobsDelphi Language BASMDelphi Language ObjectPascalDelphi Model Driven Architecture (General)Delphi Model Driven Architecture (Third Party)Delphi MultimediaDelphi Native APIDelphi Non-TechnicalDelphi ObjectPascalDelphi OLE AutomationDelphi OO designDelphi OpenToolsAPIDelphi Reporting-ChartingDelphi RTLDelphi StudentsDelphi TeamSourceDelphi Thirdparty ToolsDelphi Thirdparty Tools (General)Delphi Thirdparty Tools (IntraWeb)Delphi Thirdparty Tools (RaveReports)Delphi UpgradeDelphi VCLDelphi VCL ComponentsDelphi VCL Components UsingDelphi VCL Components WritingDelphi WebServices SOAPDelphi WinAPIDelphi XMLDelphi Installationcomp.lang.pascal.delphi.components.misccomp.lang.pascal.delphi.components.usagecomp.lang.pascal.delphi.components.writingcomp.lang.pascal.delphi.databasescomp.lang.pascal.delphi.misccomp.sources.delphi JBuilder Newsgroups----------------JBuilderJBuilder AnnouncementsJBuilder Applet IssuesJBuilder As400JBuilder CompilerJBuilder CORBA/RMIJBuilder DatabasesJBuilder DB SwingJBuilder DebuggerJBuilder DeploymentJBuilder DocumentationJBuilder EnterpriseJBuilder HandheldJBuilder IDEJBuilder JavaJBuilder JavaAPIJBuilder Java LanguageJBuilder Java SwingJBuilder Java BeansJBuilder Java Beans UsageJBuilder Java Beans DevelopmentJBuilder JBCLJBuilder JDataStoreJBuilder JobsJBuilder LinuxJBuilder MacintoshJBuilder & MobileSetJBuilder MultiLingual AppsJBuilder Non-TechnicalJBuilder OpenToolsJBuilder Servlets (JSP)JBuilder StudentsJBuilder Team DevelopmentJBuilder Thirdparty ToolsJBuilder UpgradeJBuilder Installation InterBase Newsgroups----------------InterBaseInterBase Bug DiscussionInterBase GeneralInterBase IBConsoleInterBase OpenSourceInterBase ReplicationInterBase SQLInterBase ThirdpartyInterBase Installation Miscellaneous Borland Newsgroups----------------AppCenterAppServerEnteraVisiBroker  You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum Powered by phpBB © 2001, 2006 phpBB Group SEO toolkit © 2004-2006 webmedic.
