Drag'n'Drop on buttons with em_ command depends on Parameters field

[Dalai]

Hi there.

Not sure if this is actually a bug, but it sure looks like one.

1. Start TC with a clean wincmd.ini
2. Create the following new user-defined command in usercmd.ini, either via GUI or directly in the file:

   Code: Select all

   [em_notepad]
   cmd=notepad.exe

3. Put the new em_ command on a new button, e.g. something like this:

   Code: Select all

   button40=wcmicons.dll
   cmd40=em_notepad

4. Test the button; it should launch Notepad.
5. Drag any file onto this button - you'll get the red crossed circle icon that is shown when a drop is not possible. This is not what should happen in my opinion.
6. Edit the button and add any number of characters into the Parameters field. I used a single space character since that doesn't interfere with the command itself in any meaningful way.
7. Drag a file onto the button again - now the drop is possible and Notepad will be launched with the dragged/dropped file.

To me it looks like when Parameters were added to em_ commands (in TC 11.0?) the Drag'n'Drop feature was left out by mistake; I don't think that it's intentional.

This happens because buttons with parameters are treated differently from buttons without them: Those without can hold multiple commands, e.g. cm_focusleft,em_notepad which isn't possible when there are parameters. In your specific case, TC would have to analyze the command more before deciding whether drag&drop is allowed or not. I will check whether this is feasible.

This should work now in Total Commander 11.03 RC1, please check it!

Code: Select all

05.12.23 Fixed: Allow drag&drop on buttons with user-defined commands (em_command) without parameters (32/64)

Confirm the fix for 11.03 RC1 32-bit. I haven't tested the 64-bit version yet.

[EDIT]
Fix also confirmed for the 64-bit version.
