- TimeLine
class TimeLine(gobject.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.
To improve performance, the line isn't being constructed on each call of OnDraw. It
is saved into self.savedLine as a gtk.gdk.Image. A new savedLine is constructed when
- there is no savedLine
- or project.transport.RedrawTimeLine is True
- or project.RedrawTimeLine is True
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). |

- Method resolution order:
- TimeLine
- gobject.DrawingArea
- gobject.Widget
- gobject.Object
- gobject.GObject
- atk.ImplementorIface
- gobject.GInterface
- __builtin__.object
Methods defined here:
- DrawLine(self, widget)
- Draws the timeline and saves it to memory
- Must be called initially and to redraw the timeline
after moving the project start
- GetZoomFactor(self, viewScale)
- To be used for drawing the MODE_HOURS_MINS_SECS timeline
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.
- OnDraw(self, widget, event)
- Fires off the drawing operation.
- OnStateChanged(self, obj, change=None)
- Called when there is a change of state in transport
manager or project. Could be one of
* Mode changed from bars/beats to minutes or vice versa
(requires a complete redraw of timeline - flag set)
* Change in playing position -only needs partial redraw
* Project change e.g. a scroll or zoom change
(requires a complete redraw of timeline - flag set)
- __init__(self, project, timelinebar, mainview)
- project - reference to the active project
timelinebar - reference of TimeLineBar (TimeLineBar.py)
mainview - reference to JokosherApp (JokosherApp.py) - Not used atm.
- do_size_request(self, requisition)
- moveHead(self, xpos)
- Changes the project position to the time matching xpos.
- onMouseDown(self, widget, event)
- onMouseMove(self, widget, event)
- onMouseUp(self, widget, event)
Data and other attributes defined here:
- __gtype__ = <GType TimeLine (136951352)>
