Combobox绑定事件
DrawType类可以设置绘图维度而绘图维度和坐标轴的个数是息息相关的。换言之一个比较合理的交互逻辑是改选DrawType的维度后就应该可以改变坐标轴的个数。为了实现这个功能需要为ComboBox绑定一个事件改动起来非常简单只需在initWidgets最后加上一行就可以。
def initWidgets(self, ws):if wsNone: ws [8, 3]slct ttk.Combobox(self, widthws[0], textvariableself.drawType)slct[value] self.typesslct.pack(sidetk.LEFT)slct ttk.Combobox(self, widthws[1], textvariableself.drawDim)slct[value] self.dimsslct.pack(sidetk.LEFT)slct.bind(ComboboxSelected, self.dimChanged)接下来比较重要的则是self.dimChanged的定义。由于我们希望当Combobox改变时是另一个控件的内容发生变化所以self.dimChanged最好是其他控件传入的一个函数。故而需要更改DrawType的初始化函数即添加一个func参数然后把这个参数赋给self.dimChanged方法。
def __init__(self, master, types, slctType, slctDim3, wsNone, funcNone, **options):super().__init__(master, **options)#。。。self.dimChanged func# 。。。互相调用
最后修改AxisList中初始化DrawType的语句
self.drawTypeDim DrawType(frm, types, slctType, funcself.dimChanged)并创建self.dimChanged函数代码如下逻辑是根据当前选择的维度来更新txyz这几个AxisFrame。
def dimChanged(self, evt):txyz self.getDrawDim()for flag in txyz:self.vis[flag] flag in txyzself.updateVisible()def updateVisible(self):for flag in txyz:self.afs[flag].pack_forget()for flag in txyz:if self.vis[flag]:self.afs[flag].pack(sidetk.TOP, filltk.X)
效果如下 最后的最后在坐标轴创建时也应该遵循绘图维度和坐标个数之间的关系这样打开软件或者新创建一组坐标的时候就可以自动与绘图维度相匹配了。
def initAxis(self, mode, widths):for flag in txyz:self.afs[flag] AxisFrame(self._c, flag, mode, widths)self.afs[flag].pack(sidetk.TOP, filltk.X)self.vis {L : L in self.getDrawDim() for L in txyz}self.updateVisible()
