====== Filter selection ======
In your chosen operating system (Windows/Linux/etc.), you will be aware that at any one time there will be one active window that sits above the others [//right now, I'm guessing it's this web browser//]. Similarly, in ZeoGraph, there will be one //selected// filter that sits above the others.
===== What can I do with the selected filter? =====
You may use the toolbar buttons and/or menu items listed below to edit, remove or disconnect the selected filter:
^ Button ^ Menu option ^ Description ^
| {{:plugins:calc:zeograph:userguide:window:toolbar:filteroptionsbtn.png}} | //Filter->Options// | Edit the selected filter's options. |
| {{:plugins:calc:zeograph:userguide:window:toolbar:disablefilterbtn.png}} | //Filter->Disable// | Disables or re-enables the selected filter. |
| {{:plugins:calc:zeograph:userguide:window:toolbar:disconnectfilterbtn.png}} | //Filter->Disconnect// | Disconnect the pins of the selected filter. |
| {{:plugins:calc:zeograph:userguide:window:toolbar:removefilterbtn.png}} | //Filter->Delete// | Delete the selected filter. |
===== Which filter is selected? =====
You can easily tell which filter is selected because it will be drawn with a highlighted title bar, and surrounded by a blue rectangle, as shown below:
| {{:plugins:calc:zeograph:userguide:filters:selection:filteractive.png}} | {{:plugins:calc:zeograph:userguide:filters:selection:filterinactive.png}} |
^ Selected ^ Unselected ^
The filters are drawn using the colours of the current Windows theme. In the above screenshots, I was using Vista. If you are using XP or Windows 2000, the filters will look a little differently.
===== How to I select a filter? =====
You can change which filter is selected by left-clicking on the filter to be selected. This will change a filter from the unselected state (above right) to the selected state (above left). When you do this, the previously selected filter is de-selected.
