Extend the drag and drop support of some classes

[Gesner Passos]

MWRunFiles, WorkspaceSelector, DataSelector

[Gesner Passos]

Adds the drop functionality of those classes.

[Gesner Passos]

A quick and dirty implementation of the following features:

MWRunFiles: drop functionality for any string or local file (does not accept the pattern a = mtda?)

WorkspaceSelector: drop functionality for the pattern: a = mtda? (allow selecting the workspace by dragging it from the workspace window.

DataSelector: Mixture of both. If you drop a local file, it switches to MWRunFiles if it is a workspace, it changes to the workspaceselector.

The code must be improved and documented.

[Gesner Passos]

I'm giving this to Nick to let him decide if these features should enter or not. I would also like if he could find someone to do what is necessary to improve what is proposed in the patch.

Add drag drop to mantid QT Widgets

This adds drag drop functionality to all instances of

• MWRunfiles
• WorkspaceSelector
• DataSelector

This will be on by default for all instances of the widgets, but can be disabled by calling

widget->acceptsDrops(false)

MWRunFiles will accept dropped files, and text, but NOT workspaces

WorkspaceSelector will select dropped workspaces if that selection is valid for the control

DataSelector will change to the MWRunfiles or WorkspaceSelector based on the drop and act as the control above

To Test:

1. Open up mantidplot, load a workspace or two, and have some external files ready
2. Open the SANS ISIS interface and into one of the 6 input file boxes try dropping workspaces(should not work) or files, or text from outside mantidplot (should work)
3. Open ConvertToEnergy, select IRIS and process a couple of IRIS files from autodata (just load the file and hit process.
4. Open Indirect DataAnalysis and go to the Fury tab
5. Click on the file dopdown and select workspace you should have entries for the reduced workspaces you have just created.
6. Have fun dropping owkrspaces or external files

Probably better tested by someone who's more familiar with all these ISIS interfaces. I just wanted to check it did no damage to Step Scan and DGS Reduction interfaces, which use MWRunFiles.

Tested it on all the widgets listed and it seems to work fine.
