问题描述

我想设置我的选择的切换按钮的颜色,我已经创建了面板。问题是,在我所显示我的面板上众多的切换按钮,当我想改变每个人只有最后一个按钮的颜色变化的颜色。这里是我的code:

 进口WX类帧(wx.Frame):高清__init __(个体经营):
    wx.Frame .__的init __(自我,无)
    self.panel = wx.Panel(个体经营,wx.ID_ANY)    self.sizer = wx.BoxSizer(wx.VERTICAL)
    self.flags_panel = wx.Panel(个体经营,wx.ID_ANY,风格= wx.SUNKEN_BORDER)    self.sizer.Add(self.flags_panel)
    self.SetSizer(self.sizer,wx.EXPAND | wx.ALL)
    self.flags =标志(self.flags_panel,[8,12])
    self.flags.Show()类标志(wx.Panel):
高清__init __(自我,面板,num_flags = []):#,行= 0,列= 0,半径= 0 hspace = 0产品,VSPACE = 0,x_start = 0,y_start = 0
    wx.Panel .__的init __(自我,面板,-1,大小=(350700))    NUM_ROWS = num_flags [0]
    NUM_COLUMNS = num_flags [1]
    x_pos_start = 10
    y_pos_start = 10    I = x_pos_start
    J = y_pos_start
    按钮= []
    在范围(NUM_COLUMNS)我:
        buttons.append('切换按钮')
    self.ButtonValue =假
    在按键按钮:
        指数= 0
        而指数= 15!
            self.Button = wx.ToggleButton(个体经营,-1,大小=(10,10),POS =(I,J))
            self.Bind(wx.EVT_TOGGLEBUTTON,self.OnFlagCreation,self.Button)
            self.Button.Show()
            I + = 15
            指数+ = 1
        J + = 15
        我= 10    self.Show()高清OnFlagCreation(个体经营,事件):
    如果没有self.ButtonValue:
        self.Button.SetBackgroundColour('#fe1919')
        self.ButtonValue = TRUE
    其他:
        self.Button.SetBackgroundColour('#14e807)
        self.ButtonValue =假如果__name__ =='__main__':
   应用= wx.App(假)
   帧=帧()
   frame.Show()
   app.MainLoop()


解决方案

您的问题很简单。最后一个按钮总是改变,因为它是定义的最后一个按钮:

  self.Button = wx.ToggleButton(个体经营,-1,大小=(10,10),POS =(I,J))

通过每一次循环中,你重新分配 self.Button 属性不同的按钮。你想要做的是从事件对象提取按钮并更改其背景色。因此,改变你的功能如下:

 高清OnFlagCreation(个体经营,事件):
    BTN = event.GetEventObject()
    如果没有self.ButtonValue:
        btn.SetBackgroundColour('#fe1919')
        self.ButtonValue = TRUE
    其他:
        btn.SetBackgroundColour('#14e807)
        self.ButtonValue =假

I want to set the color of a toggle button of my choice in the panel that I have created. The problem is that in the numerous toggle buttons that I have displayed on my panel when I want to change the color of each one only the color of the last button changes. Here's my code:

import wx

class Frame(wx.Frame):

def __init__(self):
    wx.Frame.__init__(self,None)
    self.panel = wx.Panel(self,wx.ID_ANY)

    self.sizer = wx.BoxSizer(wx.VERTICAL)
    self.flags_panel = wx.Panel(self, wx.ID_ANY, style = wx.SUNKEN_BORDER)

    self.sizer.Add(self.flags_panel)
    self.SetSizer(self.sizer,wx.EXPAND | wx.ALL)
    self.flags = Flags(self.flags_panel, [8,12])
    self.flags.Show()

class Flags (wx.Panel):
def __init__(self,panel, num_flags = []):#,rows = 0,columns = 0,radius = 0, hspace = 0, vspace = 0,x_start = 0, y_start = 0
    wx.Panel.__init__(self,panel,-1, size = (350,700))

    num_rows = num_flags[0]
    num_columns = num_flags[1]
    x_pos_start = 10
    y_pos_start = 10

    i = x_pos_start
    j = y_pos_start
    buttons = []
    for i in range (num_columns):
        buttons.append('toggle button')
    self.ButtonValue = False
    for button in buttons:
        index = 0
        while index != 15: 
            self.Button = wx.ToggleButton(self,-1,size = (10,10), pos = (i,j))
            self.Bind(wx.EVT_TOGGLEBUTTON,self.OnFlagCreation, self.Button)
            self.Button.Show()
            i += 15
            index += 1
        j += 15
        i = 10

    self.Show()

def OnFlagCreation(self,event):
    if not self.ButtonValue:
        self.Button.SetBackgroundColour('#fe1919')
        self.ButtonValue = True
    else:
        self.Button.SetBackgroundColour('#14e807')
        self.ButtonValue = False

if __name__ == '__main__':
   app = wx.App(False)
   frame = Frame()
   frame.Show()
   app.MainLoop()

解决方案

Your problem is quite simple. The last button is always changed because it's the last button defined:

self.Button = wx.ToggleButton(self,-1,size = (10,10), pos = (i,j))

Each time through the for loop, you reassign the self.Button attribute to a different button. What you want to do is extract the button from your event object and change its background color. So change your function to look like this:

def OnFlagCreation(self,event):
    btn = event.GetEventObject()
    if not self.ButtonValue:
        btn.SetBackgroundColour('#fe1919')
        self.ButtonValue = True
    else:
        btn.SetBackgroundColour('#14e807')
        self.ButtonValue = False
