Ahh now I understand!
there is the code for setting the toolbar:
Code:
def addGridSize(self,widget):
def setSize(data):
ACTION.SET_GRAPHICS_GRID_SIZE(data)
print INFO.GRID_INCREMENTS
for temp in (INFO.GRID_INCREMENTS):
if temp == '0':
sizeAct = QtWidgets.QAction('Off', widget)
sizeAct.triggered.connect(lambda: setSize(0))
widget.addAction(sizeAct)
continue
i = self.parse_increment(temp)
sizeAct = QtWidgets.QAction('%s'%temp, widget)
# weird lambda i=i to work around 'function closure'
sizeAct.triggered.connect(lambda state, i=i: setSize(i))
widget.addAction(sizeAct)
# We convert INI parced increments to machine units
def parse_increment(self, gridIncr):
if gridIncr.endswith("mm"):
scale = self.conversion(1)
elif gridIncr.endswith("cm"):
scale = self.conversion(10)
elif gridIncr.endswith("um"):
scale = self.conversion(.001)
elif gridIncr.endswith("in") or gridIncr.endswith("inch"):
scale = self.conversion(1., metric = False)
elif gridIncr.endswith("mil"):
scale = self.conversion(.001, metric = False)
else:
scale = 1
incr = gridIncr.rstrip(" inchmuil")
if "/" in incr:
p, q = incr.split("/")
incr = float(p) / float(q)
else:
incr = float(incr)
LOG.debug("parceed: text: {} Increment: {} scaled: {}".format(gridIncr, incr, (incr * scale)))
return incr * scale
# This does the conversion
# calling function must tell us if the data is metric or not.
def conversion(self, data, metric = True):
if INFO.MACHINE_IS_METRIC:
if metric:
return INFO.convert_metric_to_machine(data)
else:
return INFO.convert_imperial_to_machine(data)
else:
if metric:
return INFO.convert_metric_to_machine(data)
else:
return INFO.convert_imperial_to_machine(data)
it reads the raw grid increments found in the INI fle.
It then parses them, converting the text 'in' and 'mm' etc to machine units.
if the action is triggered:
ACTION.SET_GRAPHICS_GRID_SIZE(data)
sets the grid of the graphics display
Hope that helps.
