I'm writing a script button in which I want to transform some outline data
into html and then display that html in a leo doc. The viewrendered
functionality doesn't seem to really fit my needs as the render pane output
is tied to whatever node is currently selected.
I just want to be able to display the html "on-demand" (i.e. through script
button click) and refresh it on-demand.
I have working code for it, but it requires storing the dock object
somewhere so it can be used again the next time the script is called. I was
wondering if there is some good, already-established convention for storing
"global" state for scripts.
In my case, the variable makes sense to be on a per-commander basis, so I
just stored my information on the commander 'c'. That doesn't seem very
clean to me and I was wondering if there is a better approach?
Here is my function which stores and uses global state on c:
def display_widget_in_leo_pane(c, w, name):
"""
w is the widget to display
name is the name the widget should appear in pane menu
"""
dw = c.frame.top
if not hasattr(c, '*my_docks*'): c.my_docks = {}
dock = c.*my_docks*.get(name)
if not dock:
dock = g.app.gui.create_dock_widget(
closeable=True, moveable=True, height=50, name=name)
c.*my_docks*[name] = dock
dw.addDockWidget(QtCore.Qt.RightDockWidgetArea, dock)
dock.setWidget(w)
dock.show()
And a function to use the above:
def display_html(html, name = 'test html'):
w = QtWidgets.QTextBrowser()
w.setHtml(html)
display_widget_in_leo_pane(c, w, name)
Also, could someone comment on whether the above code is "leaking" widgets?
Should I be calling dock.widget() to retrieve the old widget each time to
perform some sort of delete/cleanup?
