The program I'm modifying uses Tkinter widgets and passes values
between a non-Tkinter (OperationalSettings class) object and an object
of class OperationalSettingsDialog(tkSimpleDialog.Dialog). The former
saves changed dialog values in the main program, Sentuser_GUI (main
loop), via (global) self variables, which are initially set by
Sentuser_GUI. The latter object just manages the GUI and communicates
changed values. Control variables are used and they are hard-coded
into assignment statements. I'm trying to remove the hard-coding, and
allow assignment to the GUI self variables, while maintaining types. >From Sentuser_GUI, =============Sentuser========== self.settingsMenu = Menu(menu) menu.add_cascade(label="Settings",menu=self.settingsMenu) self.settingsMenu.add_command(label="Schedule, Site, and Operation...", command=self.OperationalSettings) ... ===========End Sentuser========= sets up a top level menu for the dialog and menu item settingsMenu, which is a dialog. >From OperationalSettings, ==============Op Settings======== def OperationalSettings(self): print "OSett self = ", self, "type =", type(self) set_loc_dict = {} set_loc_dict[ "ok" ] = False set_loc_dict[ "color" ] = 2 if self.gray_scale: set_loc_dict[ "color"] = 1 set_loc_dict[ "hourly_rate" ] = self.hourly_rate set_loc_dict["start_time"] = self.start_time ... dialog = OperationalSettingsDialog( self.master, set_loc_dict ) ... if dialog.colorVar.get() == 1: self.gray_scale = True else: self.gray_scale = False ... ===========End Op Settings======== Part of OperationalSettingsDialog is shown below. The self.gray_scale coding example is hard-code that needs to be replaced to allow the type to remain the same for (configuration) names like gray_scale to be pulled from a list, and yet make an assignment as boolean or whatever type is associated with the name. There are 20+ names. The True (boolean notion) is really only available from dialog.colorVar.get(), so how can I set self.gray_scale to a boolean value? I don't see how setattr will help here. The name list does show the type corresponding to the name, but it seems of no real value. OperationalSettingsDialog uses control variables, as in, =================Op Settings Dialog================ class OperationalSettingsDialog(tkSimpleDialog.Dialog): def __init__(self, parent, sdict): self.sdict = sdict tkSimpleDialog.Dialog.__init__(self, parent) def body(self,master): self.title("Operational Settings") self.colorVar = IntVar() Radiobutton( master, text="Gray Scale", value=1, variable=self.colorVar).grid(row=0, sticky=W) ... =============End Settings Dialog======== --
