I have a listbox containing filenames and want to drag a file from it to another non-PxPlus-application. How can I do that?

You can allow external applications to drop file names onto a list box by using this directive.
DROP FILE ON dest_ctl_id RETURN new_ctl_id
Whenever a file is dropped onto the dest_ctl_id control, the system will generate the CTL event specified by new_ctl_id.
The application can get a list of the file pathnames being dropped from the FIN(0, "DROPFILES") function call. All pathnames will be fully expanded and separated by a SEP character.
This can be found in the docs here: https://manual.pvxplus.com/?directives/drop_on.htm#filedrop

Devon,
I want to drag files from a PxPlus listbox and drop it on a control of an external application.

PxPlus doesn't have the ability to directly provide a list box that you drag files out of, however what you can do is if the files you want to drag can be placed in a directory you can create a Shell.Explorer control on your PxPlus panel pointing to that directory. Then the user can drag the files out to external applications.
For example:
def object h,@(10,10,30,10)="Shell.Explorer"
h'navigate2("c:\pvxsrc\workarea")
This will create you a window where the directory will be listed and the user can drag the files out of.
One trick you can use if you have a large selection of files in a common directory but only want to allow the user to select specific files is to create a dummy directory then using the Windows mklink command create links to just the files you want the user to have access to.

Thank you. I'll take a look at it.
