Other Types
Design Time Editors
| Editor class |
Description |
| TPJExtFileFilterExtPE |
Property editor for the Extensions property of the TPJExtFileFilter component. This editor displays a dialogue box where extensions can be added, removed and saved in the correct format. |
| TPJDropFilesCE |
Component editor that causes an event handler for the OnDropFiles events of the drop file components to be opened in the designer when the components are double-clicked. The default action without this component editor is to open the rarely used OnBeforeDrop event handler, which is not very useful. |
