class TimeLine(gtk.DrawingArea) |
|
This class handles drawing the time line display. The time line is part of the
TimeLineBar. TimeLine displays the time in minutes/seconds (MODE_HOURS_MINS_SECS)
or bars and beats (MODE_BARS_BEATS). These modes are set in project.transport.
When the time line is constructed in MODE_HOURS_MINS_SECS, it dynamically adjusts
its scale to the project.viewScale. MODE_BARS_BEATS does not support this (yet). |

- TimeLine
- gtk.DrawingArea
- gtk.Widget
- gtk.Object
- gobject._gobject.GObject
- atk.ImplementorIface
- gtk.Buildable
- gobject.GInterface
- __builtin__.object
Methods defined here:
- DrawLine(self)
- Uses Cairo to draw the timeline onto a canvas in memory.
Must be called initially and to redraw the timeline
after moving the project start.
Parameters:
allocation -- the gtk.gdk.Rectangle allocated to the widget.
- GetZoomFactor(self, viewScale)
- To be used for drawing the MODE_HOURS_MINS_SECS timeline.
Parameters:
viewScale -- the view scale in pixels per second.
Returns:
- an integer factor to be multiplied with the viewScale to zoom the timeline in/out
- a boolean indicating if milliseconds should be displayed
The default factor is 1000, meaning that the distance between the short lines of the timeline
symbolizes 1000 milliseconds. The code will increase of decrease this factor to keep the
timeline readable. The factors can be set with the zoomLevels array. This array
contains zoom levels that support precision from 20 ms to 1 minute. More extreme zoom
levels could be added, but will never be reached because the viewScale is limited.
- OnAllocate(self, widget, allocation)
- From:
http://www.moeraki.com/pygtkreference/pygtk2reference/class-gtkwidget.html#signal-gtkwidget--size-allocate
The "size-allocate" signal is emitted when widget is given a new space allocation.
Parameters:
widget -- reserved for GTK callbacks.
allocation -- the gtk.gdk.Rectangle allocated to the widget.
- OnDraw(self, widget, event)
- Fires off the drawing operation.
Parameters:
widget -- reserved for GTK callbacks, don't use it explicitly.
event -- reserved for GTK callbacks, don't use it explicitly.
- OnProjectTimelineChange(self, project)
- Callback for signal when time signature, zoom level,
bpm or view start of the project change. All of these things
effect the way that the timeline is drawn.
Parameters:
project -- the project instance that send the signal.
- OnTransportMode(self, transportManager, mode)
- Callback for signal when the transport mode changes.
Parameters:
transportManager -- the TransportManager instance that send the signal.
mode -- the mode type that the transport changed to.
- OnTransportPosition(self, transportManager, extraString)
- Callback for signal when the transport position changes.
Parameters:
transportManager -- the TransportManager instance that send the signal.
extraString -- a string specifying the extra action details. i.e. "stop-action"
means that the position changed because the user hit stop.
- SetAccessibleName(self)
- Set a name property in ATK to help users with screenreaders.
- __init__(self, project, mainview)
- Creates a new instance of TimeLine
Parameters:
project - reference to Project (Project.py)
mainview - reference to JokosherApp (JokosherApp.py) - Not used atm.
- do_size_request(self, requisition)
- From:
http://www.moeraki.com/pygtkreference/pygtk2reference/class-gtkwidget.html#signal-gtkwidget--size-request
The "size-request" signal is emitted when a new size is
requested for widget using the set_size_request() method.
Parameters:
requisition -- the widget's requested size as a gtk.Requisition.
- moveHead(self, xpos)
- Changes the project position to the time matching xpos.
Parameters:
xpos -- the time of the new project position.
- onMouseDown(self, widget, event)
- Called when a mouse button is clicked.
Parameters:
widget -- reserved for GTK callbacks, don't use it explicitly.
event -- reserved for GTK callbacks, don't use it explicitly.
Returns:
True -- to continue the GTK signal propagation.
- onMouseMove(self, widget, event)
- Called when the mouse pointer has moved.
Parameters:
widget -- reserved for GTK callbacks, don't use it explicitly.
event -- reserved for GTK callbacks, don't use it explicitly.
- onMouseUp(self, widget, event)
- Called when a mouse button is released.
Parameters:
widget -- reserved for GTK callbacks, don't use it explicitly.
event -- reserved for GTK callbacks, don't use it explicitly.
- onUpdateAutoscroll(self)
