• DROPINFO NAME is the file name portion of the path, including the extension

On the object Properties screen, check the "Drop?" box, and set the Chooser Mode to one of the following:

• ANY - Accepts a file, folder, or Email message/Attachment.
• FILE - Accepts files only.
• FOLDER - Accepts Folder names only
• TREE - Same as ANY, except if the user drops a folder name, the folder will be parsed and all file names will be returned in the DROPINFO/DROPPROP files.

You can also set those values, --- WIDGET DROP TARGET and --- WIDGET FI CHOOSE MODE, via ILF code.

The DROPINFO file

• DROPINFO PATH contains the full path to the object the user dropped
• DROPINFO NAME is the file name portion of the pat, including the extension
• DROPINFO EXT has the file extension
• DROPINFO TYPE shows the item type (file, folder, etc.)
• DROPINFO SIZE contains the size of the object

      SET      --- TEMP 512                   =      "
      APPEND   --- TEMP 512                   0  --- DROPINFO PATH
      APPEND   --- TEMP 512                   0      "
      PASS     --- TEMP 512                   FIELD            SHARE? N
      GOSUB    --- .CLIENT LOAD URL

Example:

      IF       --- OPTION                     EQ     DROP

TTT   DISPLAY  --- TEMP 256                   (AT APPEARANCE #    )

• FILE. Accepts files only.
• FOLDER. Accepts Folder names only
• TREE. Same as ANY, except if the user drops a folder name, the folder will be parsed and all file names will be returned in the DROPINFO/DROPPROP files.

      SET      --- TEMP 512                   =      "
      APPEND   --- TEMP 512                   0  --- DROPINFO PATHNAME
      APPEND   --- TEMP 512                   0      "
      PASS     --- TEMP 512                   FIELD            SHARE? N
      GOSUB    --- .CLIENT LOAD URL

Creating Drop Target

@SDND

Drop Target at Runtime

When the user drops an object (file/folder/email message/etc) on the drop target, Appx will populate 2 files and then fire the specified --- OPTION. The files are: --- DROPINFO which will contain one record for every object dropped and --- DROPPROP which will contain multiple records for each object dropped. Both of these files are keyed by the --- WIDGET IMAGE KEY, so if you have more than one drop target on your image, you can differeniate them. Alternatively, you can have the different drop targets fire different Option Numbers.

The --- DROPINFO PATHNAME contains the full path to the object the user dropped. The --- DROPROP file is a child file of --- DROPINFO and contains multiple records for each object. The specific data varies depending on the type of object dropped. The --- DROPPROP KEYWORD identifies a specific property, and --- DROPPROP VALUE contains the value of that property.

For example, if a file from the users desktop is dropped, --- DROPINFO PATHNAME might contain something like "C:\Documents and Settings\jean\Desktop\VolumeC.txt" and --- DROPPROP might contain the following keywords and values:

An Email message might have the following ---- DROPROP keywords and values:

Note that these files are cleared every time the user drops an object on your drop target. If you do not process or save the information each time, the previous data will be lost.

Drag & Drop Support

You can now define a Widget as the target of a drag & drop operation.

Note: Screen shots and more detailed information will be provided as these details are finalized.

Overview:

You can now define certain Widget types (Buttons, Labels, others?) as targets of a drag & drop operation. This means the user can drag a file or other object to Appx Widget & drop it.
