This extension implements a pane at the top of each IDLE edit window which provides block structure hints. These hints are the lines which contain the block opening keywords, e.g. 'if', for the -enclosing block. The number of hint lines is determined by the numlines +enclosing block. The number of hint lines is determined by the maxlines variable in the codecontext section of config-extensions.def. Lines which do not open blocks are not shown in the context hints pane. @@ -80,7 +80,7 @@ class CodeContext: def reload(cls): "Load class variables from config." cls.context_depth = idleConf.GetOption("extensions", "CodeContext", - "numlines", type="int", default=3) + "maxlines", type="int", default=15) ## cls.bgcolor = idleConf.GetOption("extensions", "CodeContext", ## "bgcolor", type="str", default="LightGray") ## cls.fgcolor = idleConf.GetOption("extensions", "CodeContext", @@ -116,7 +116,7 @@ class CodeContext: padx += widget.tk.getint(widget.cget('padx')) border += widget.tk.getint(widget.cget('border')) self.label = tkinter.Label( - self.editwin.top, text="\n" * (self.context_depth - 1), + self.editwin.top, text="", anchor=W, justify=LEFT, font=self.textfont, bg=self.bgcolor, fg=self.fgcolor, width=1, # Don't request more than we get. @@ -191,11 +191,10 @@ class CodeContext: stopindent) self.info.extend(lines) self.topvisible = new_topvisible - # Empty lines in context pane. - context_strings = [""] * max(0, self.context_depth - len(self.info)) - # Followed by the context hint lines. - context_strings += [x[2] for x in self.info[-self.context_depth:]] - self.label["text"] = '\n'.join(context_strings) + # Last context_depth context lines. + context_strings = [x[2] for x in self.info[-self.context_depth:]] + showfirst = 0 if context_strings[0] else 1 + self.label["text"] = '\n'.join(context_strings[showfirst:]) def timer_event(self): "Event on editor text widget triggered every UPDATEINTERVAL ms." |
