I suspect that there is a bit more to the story than the code you posted. Are you sure that you are not creating a new TMouseButton type in ScrollBoxEx ? - Delphi seems to think that you are doing that Back to top daniel Guest Posted: Thu Dec 11, 2003 12:34 pm    Post subject: Re: PanelsMouseDown - incompatible types allo J, you wrote, Quote: Are you sure that you are not creating a new TMouseButton type in ScrollBoxEx ? yes and the procedure was the one as i posted and in fact the implementation for that precedure has not been coded yet as :- procedure TScrollBoxEX.PanelsMouseDown(Sender : TObject; Button : TMouseButton; Shift : TShiftState; x,y : Integer ); begin { no code yet} end; your help will be most appreciated else i am stuck. nb: any thing to do with compiler directives. ciao daniel "J French" <erewhon (AT) nowhere (DOT) com> wrote Quote: On Thu, 11 Dec 2003 18:47:23 +0800, "daniel" wrote: allo, sample code : type TScrollBoxEx = class(TScrollBox) private procedure PanelsMouseDown(Sender : TObject; Button : TMouseButton; Shift: TShiftState; x,y: Integer ); end; in the constructor, aPanel[indx].onMouseDown := PanelsMouseDown; the compiler gave this error :- incompatible types: 'Controls.TMouseButton' and 'scrollboxex.TMouseButton' do advise for what can i do to overcome that.

The first thing I would try is to alter TMouseButton to: Controls.TMouseButton If that makes things behave then I would undo the changes, Right Click on the various TMouseButtons and use Find Declaration The problem is almost certainly something fishy about your Uses list - my guess would be some flashy 3rd party stuff has redefined TMouseButton to cater for the latest innovation Back to top daniel Guest Posted: Thu Dec 11, 2003 2:26 pm    Post subject: Re: PanelsMouseDown - incompatible types allo J. i'd added the Controls.TMouseButton and a recompile this time has no error. your thought of the third party component could be true but meanwhile take a look at the following where there is a similar error of type incompatiblity :- code sample :- constructor TScrollBoxEx.Create(AOwner: TComponent); begin inherited Create(AOwner); BorderStyle := bsNone; ...... end; now the compiler gave an error like: Incompatible types:'forms.TBorderStyle' and 'scrollboxex.TBorder' what should i do for that. ciao daniel "J French" <erewhon (AT) nowhere (DOT) com> wrote Quote: On Thu, 11 Dec 2003 20:34:25 +0800, "daniel" wrote: allo J, you wrote, Are you sure that you are not creating a new TMouseButton type in ScrollBoxEx ? yes and the procedure was the one as i posted and in fact the implementation for that precedure has not been coded yet as :- procedure TScrollBoxEX.PanelsMouseDown(Sender : TObject; Button : TMouseButton; Shift : TShiftState; x,y : Integer ); begin { no code yet} end; your help will be most appreciated else i am stuck. nb: any thing to do with compiler directives.

My hunch is that you had a 3rd party Unit somewere in your App And that it had redefined TMouseButton It could even be the case that some smart Alec had provided a hacked version of Controls.pas The thing to do is to check one's Uses list very carefully - and keep it trimmed to the minimum Also to be very careful of 3rd party stuff 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.
