View source for QGIS TUFLOW Increment Layer

This tool can be found in the '''TUFLOW >> Editing >> Increment Selected Layer''' menu item.<br>
As the name implies, this tool takes the active layer (as selected in the layer control) and saves a copy of this with a new filename.  The currently open file will be closed and the new version opened, this avoids accidentally modifying the superseded version!<br>
The dialogue looks like the below.<br>

The components are described below.
<ol>
<li>Drop box for selecting the layer to be incremented.  This defaults to the current layer in the layer control.</li>
<li>Keep source formatting.  By enabling this checkbox a style .qml will be created from the existing layer and this will be applied to the new layer, so any custom styling will be preserved.</li>
<li>Output Folder.  The location for the folder to be saved into.  This defaults to the location of the current file and is updated if the '''Source Layer''' dropbox is changed.</li>
<li>Output Filename.  The output file, the tool will attempt to guess a filename by incrementing the current filename by 1.  For example the source layer with name '''2d_code_M01_001_R''' will guess '''2d_code_M01_002_R'''.   This will be updated if the '''Source Layer''' dropbox is changed.</li>
<li>Browse.  Use the a file dialogue to set the output folder (item 3 above) and output filename (item 4 above).</li>
<li>Standard buttons. OK to proceed and Cancel to quit the tool</li>
</ol>
The tool also checks if an existing file with the name and location specified already exists, if so, an error is displayed and the tool will close.
