Detailed Description
Expand on the summary, if appropriate. A couple of sentences suffices to explain the goal, but the more details you can provide the better.
Benefit to Sugar
Standard gtk components are not designed to be lazy. Third party widgets, I managed to find, uses scheme with renders(like gtk components), introduced component uses widgets instead(could have performance penalties, I guess, in common case but we don't have many rows in Journal view, so should be ok for us).
Benefits we have for such scheme:
- coding cells is more useful by using widgets then renders, we can reuse our existed custom widgets instead of coding sugarized cell renders
- in some cases its hard to sugarize cells theme(we still have ugly progress bar for Journal entries), with new widget, we use just gtk.ProgressBar
Scope
- new widget for sugar-toolkit
UI Design
Nothing.
How To Test
Simple example for SmootTable widget
import gtk
from sugar.graphics.smoothtable import SmoothTable
window = gtk.Window()
scrolled = gtk.ScrolledWindow()
scrolled.set_policy(gtk.POLICY_ALWAYS, gtk.POLICY_ALWAYS)
window.add(scrolled)
class Cell(gtk.Button):
def do_fill_in(self, table, row, column):
self.props.label = '%s:%s' % (row, column)
table = SmoothTable(Cell, 3, 3)
table.row_count = 100
scrolled.add(table)
window.show_all()
gtk.main()
