DesignIntf
DesignIntf defines the interfaces and classes used by the property editors in the IDE.
RAD Studio gives you the chance to use DesignIntf from a package or a DLL source. Below you can find the best approach to use it in both cases.
Contents
Using DesignIntf from a Package.
As IDE plugins are mostly packages, and they use DesignIntf unit, the most common way to use it is to add the designide file to the Requires folder, as shown below:
- In the Projects window, expand the Package1.bpl node.
- Right-click the Requires file and select Add Reference…
- When the Add window opens, type
designide.dcpin the Package name field. - Once you click OK, you should see a
designide.dcpfile created below the Requires file.
After adding the package name, the compiler automatically recognizes that your package uses the designide package.
Using DesignIntf from a DLL.
To use the DesignIntf and DesignEditors units from a DLL with Delphi, you need to link to the designide package. To link it successfully, add the –LUDesignIDE to the Compiler options:
- In the menu bar, click Project and select Options to open the Project Options dialog box.
- Under Delphi Compiler, select Compiling.
- Under the Other options section, look for Additional options to pass to the compiler, and type
–LUDesignIDE.
With C++, you need to ensure that $(BDS)\include\windows\vcl\design is added to the INCLUDE path and that the designide.bpi is added to the Requires folder of your package.
For more information, see the comments in the source; the DesignIntf.pas source file is liberally commented.
