* grc: prevent search keystrokes from modifying flowgraph, take twoClayton Smith2020-08-201-1/+2
| | | | | | | | | | | | | | | | | After blocks are unselected, it's necessary to trigger an Action so that keystroke action handlers will be updated in Application._handle_action. In my previous pull request, I achieved this by replacing a FlowGraph.update_selected() call with a FlowGraph.update_selected_elements() call, since the latter happens to trigger an Action. However, this does not occur in all cases, because FlowGraph.update_selected_elements() can return early. To fix the issue, I've reverted that change and changed the DrawingArea's focus-out-event handler to explicitly trigger Actions.ELEMENT_SELECT(). After this change, blocks appear to be unselect in all cases when accessing the block search box.
* grc: prevent search keystrokes from modifying flowgraphClayton Smith2020-08-191-11/+7
| | | | | | | | | | | | | | | A confluence of bugs introduced while updating GRC to Python 3 results in keystrokes being sent to the drawing area while typing in the block search box. First, the drawing area needs to be placed in a Viewport before being added into a ScrolledWindow. Fixing this allows the drawing area to grab focus as intended when it is clicked. Second, the drawing area needs to unselect all blocks when it loses focus so that the relevant keystroke actions can be disabled. This functionality was commented out during the transition to Python 3, and I've restored it here.
* python: Remove unnecessary 'from __future__ import'Oleksandr Kravchuk2020-08-031-1/+0
| | | | | | | | | | | | | | | | All of the removed `from __future__ import` were needed in older versions of Python (mostly 2.5.x and below) but later became mandatory in most versions of Python 3 hence are not necessary anymore. More specifically, according to __future__.py[1]: - unicode_literals is part of Python since versions 2.6.0 and 3.0.0; - print_function is part of Python since versions 2.6.0 and 3.0.0; - absolute_import is part of Python since versions 2.5.0 and 3.0.0; - division is part of Python since versions 2.2.0 and 3.0.0; Get rid of those unnecessary imports to slightly clean up the codebase.

* grc: prevent scrolling to top of canvasJosh Morman2019-08-071-1/+6
| | | | | | | | | | | GRC was scrolling to the top of the canvas when clicking. This occurs when clicking into the console or search tree then back into the canvas, the view is reset to the top left. Commented out one line in _handle_mouse_button_press in DrawingArea.py - makes the problem go away. Fixes #2660
