Pure Python gestures
-
@Drizzel, below works to separate the two gestures, but we lose the visual feedback for the tap selection, you would need to implement that yourself.
Better would be to find the built-in tap and give our doubletap preference over it, but I could not (yet...?) find it on the tableview, cell, content view, or the label.
import ui import gestures def double_tap(data): print('double tapped row', data.view.row) def tap(data): print('tapped', data.view.row) def tableview_cell_for_row(tableview, section, row): data = tableview.data_source.items[row] cell = ui.TableViewCell('subtitle') cell.selectable = False cell.text_label.text = data cell.row = row doubler = gestures.doubletap(cell, double_tap) tapper = gestures.tap(cell, tap) doubler.before(tapper) return cell class Delegate(): def tableview_did_select(self, tableview, section, row): print('selected row', row) tv = ui.TableView(allows_selection=False) tv.delegate = Delegate() tv.data_source = ui.ListDataSource([str(x) for x in range(5)]) tv.data_source.delete_enabled = False tv.data_source.tableview_cell_for_row = tableview_cell_for_row tv.present('fullscreen')

@mikael thanks, that works. I just change the cell‘s background color to lightgrey for visual feedback
-
@stephen True, I corrected it :) The code was a bit rushed 🤷♂️
-
awesome 😎🤓😊

@Drizzel, here’s a version that supports both the doubletap and regular row selection.
import ui import gestures def double_tap(data): print('double tapped row', data.view.row) def tableview_cell_for_row(tableview, section, row): data = tableview.data_source.items[row] cell = ui.TableViewCell('subtitle') cell.text_label.text = data cell.row = row doubler = gestures.doubletap(cell, double_tap) doubler.recognizer.delaysTouchesBegan = True return cell class Delegate(): def tableview_did_select(self, tableview, section, row): print('selected row', row) tv = ui.TableView() tv.delegate = Delegate() tv.data_source = ui.ListDataSource([str(x) for x in range(5)]) tv.data_source.delete_enabled = False tv.data_source.tableview_cell_for_row = tableview_cell_for_row tv.present('fullscreen')

hi, i found another bug, after i use 5 fingers to switch app and get back, multi-touch would be not working
-
@mikael Do you think it would be possible to use you gestures module on an objectiveC object?
I want to add gestures on a SceneView object, but functions like tap require their view parameter as an object having objc_instance property (see UIGestureRecognizerDelegate init).
-
@mikael I solved it with
def scene_view_tap(self,sender): location = self.recognizer.locationInView_(self.scene_view) node = self.scene_view.hitTest_options_(location,None) print(node) . . . self.gesture_recognizer_target = ui.Button() self.gesture_recognizer_target.action = self.scene_view_tap UITapGestureRecognizer = ObjCClass('UITapGestureRecognizer') self.recognizer = UITapGestureRecognizer.alloc().initWithTarget_action_(self.gesture_recognizer_target, sel('invokeAction:')).autorelease() scene_view.addGestureRecognizer_(self.recognizer) self.scene_view = scene_view
-
@cvp, forgot to advertise earlier that the latest version of gestures in the ui3 module accepts ObjC views in addition to ui module views.
from ui3.gestures import * tap(objc_view, handler)
-
@mikael thanks, I'll try
Édit: done, ok
Re-Edit: marvelous module -
