This section of the Drop Files Components documentation describes the API exposed by the components to programmers.
| Unit | Description |
|---|---|
| PJDropFiles | Contains three components that support file drag and drop from Windows Explorer along with subsidiary components that can filter dropped files. |
| PJDropFilesDsgn | Contains the design time elements of the drop files components: a component editor, a property editor and the component and editor registration code. |
| Component | Description |
|---|---|
| TPJDropFiles | Container control that catches files dragged and dropped onto its client area or the client area of child controls. |
| TPJFormDropFiles | Non-visual component that catches files dragged and dropped onto the form that contains the component. |
| TPJCtrlDropFiles | Non-visual component that catches files dragged and dropped onto an associated control. |
| TPJExtFileFilter | File filter component that filters files according to their extension. |
| TPJWildCardFileFilter | File filter component that filters files according to a DOS-style wild card. |
| TPJFileFilter | An abstract base class for file filter components. |
| Type | Description |
|---|---|
| TPJDropFilesOption & TPJDropFilesOptions | Enumerated type and set that define the possible values of the Options property of the drop files components. |
| TPJDroppedFileFilter | Type of OnFileFilter events of the drop files components. |
| TPJExtFileFilterStyle | Enumeration representing the kind of filtering performed by the TPJExtFileFilter.Style property. |
| 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. |
