在 Python 中从 wxFormBuilder 访问特定的 sizer
Access a specific sizer from wxFormBuilder in Python
我已经使用 wxFormBuilder 构建了一个 GUI，并希望在 GUI 中动态添加按钮到 sizer。这是 wxFormBuilder 代码。

我想向 m_panel71 的子 bSizer86 添加按钮。
这是我到目前为止尝试过的方法。
class HvDocs(HighVoltage):
def __init__(self, parent):
HighVoltage.__init__(self, parent)
con = sqlite3.connect('hsmanagement.sqlite')
cur = con.execute('SELECT employee FROM employees WHERE hv=1 ORDER BY employee')
result = cur.fetchall()
con.close()
print result
sizer = self.GetSizer()
print type(sizer)
for f in range(0, len(result) ):
sizer.Add(wx.Button(self, label=str(result[f][0]), id=int(f), size=(200, 40)), 2, wx.CENTER)
我尝试了 sizer = self.GetSizer() 的一些变体，例如 sizer = self.m_panel71 和 sizer = self.GetSizer(self.m_panel71)，但我所能做的就是将按钮添加到顶级 sizer84。我如何获得 bSizer86 的访问权？
请参阅以下最小示例，了解如何仅按名称查找面板、按钮和大小调整器。 wxFormBuilder 提供了为要跟踪的 GUI 元素设置 wx.Window 属性 window_name 的可能性。您应该能够找到您需要知道的控件，使用 parent.FindWindowByName(…) 这个名称而不依赖 class 属性。
import wx
TOK_PNL = 'window_name pnl'
TOK_BTN = 'window_name btn'
def on_btn(evt, parent):
btn = parent.FindWindowByName(TOK_BTN)
pnl = parent.FindWindowByName(TOK_PNL)
newbtn = wx.Button(pnl, -1, 'newbtn')
szsub = btn.GetContainingSizer()
szsub.Add(newbtn, 1, wx.EXPAND|wx.ALL, 4)
pnl.Layout()
class testfrm(wx.Frame):
def __init__(self, *args, **kwds):
wx.Frame.__init__(self, *args, **kwds)
pnl = wx.Panel(self, -1)
pnl.SetName(TOK_PNL)
btn = wx.Button(pnl, -1, 'Add Button')
btn.SetName(TOK_BTN)
szmain = wx.BoxSizer(wx.VERTICAL)
szsub = wx.BoxSizer(wx.HORIZONTAL)
szsub.Add(btn, 0, wx.EXPAND|wx.ALL, 4)
szmain.Add(szsub)
pnl.SetSizer(szmain)
the_parent = self
btn.Bind(wx.EVT_BUTTON, lambda evt: on_btn(evt, the_parent))
if __name__ == '__main__':
app = wx.App(redirect=False)
frm = testfrm(None, -1, 'testfrm')
frm.Show()
app.MainLoop()
在进一步挖掘和尝试之后，我终于用下面的代码解决了我的问题
sizer = self.m_button67.GetContainingSizer()
self.m_button67.Destroy()
self.m_staticText = wx.StaticText( self.m_panel74, wx.ID_ANY, label= "Ladder ID")
sizer.Add( self.m_staticText, 0, wx.ALL, 5 )
self.m_staticText = wx.StaticText( self.m_panel74, wx.ID_ANY, label= "Engineer")
sizer.Add( self.m_staticText, 0, wx.ALL, 5 )
self.m_staticText = wx.StaticText( self.m_panel74, wx.ID_ANY, label= "Description")
sizer.Add( self.m_staticText, 0, wx.ALL, 5 )
self.m_staticText = wx.StaticText( self.m_panel74, wx.ID_ANY, label= "Last Check")
sizer.Add( self.m_staticText, 0, wx.ALL, 5 )
self.m_staticText = wx.StaticText( self.m_panel74, wx.ID_ANY, label= "Next Check")
sizer.Add( self.m_staticText, 0, wx.ALL, 5 )
for f in range(0, len(ladder_data)):
self.m_button = wx.Button( self.m_panel74, id=int(f), label=str(ladder_data[f][0]))
self.Bind(wx.EVT_BUTTON, self.detect_on_button)
sizer.Add( self.m_button, 0, wx.ALL, 5 )
self.m_staticText = wx.StaticText( self.m_panel74, wx.ID_ANY, label= str(ladder_data[f][1]))
sizer.Add( self.m_staticText, 0, wx.ALL, 5 )
self.m_staticText = wx.StaticText( self.m_panel74, wx.ID_ANY, label= str(ladder_data[f][2]))
sizer.Add( self.m_staticText, 0, wx.ALL, 5 )
self.m_staticText = wx.StaticText( self.m_panel74, wx.ID_ANY, label= str(ladder_data[f][3]))
sizer.Add( self.m_staticText, 0, wx.ALL, 5 )
self.m_staticText = wx.StaticText( self.m_panel74, wx.ID_ANY, label= str(ladder_data[f][4]))
sizer.Add( self.m_staticText, 0, wx.ALL, 5 )
self.m_panel74.SetSizer( sizer )
self.m_panel74.Layout()
sizer.Fit( self.m_panel74 )
真正的关键是 GetContainingSizer() 的发现。
将其与在 wxFormBuilder 中设置的虚拟按钮一起使用 (self.m_button67)
sizer = self.m_button67.GetContainingSizer()
让你成为 sizer
使用
删除虚拟按钮
self.m_button67.Destroy()
添加小工具
self.m_staticText = wx.StaticText( self.m_panel74, wx.ID_ANY, label= str(ladder_data[f][1]))
sizer.Add( self.m_staticText, 0, wx.ALL, 5 )
布局完成
self.m_panel74.SetSizer( sizer )
self.m_panel74.Layout()
sizer.Fit( self.m_panel74 )
希望这对遇到同样问题的人有所帮助。
可能有点晚了，
我相信您在错误的元素上使用了 GetSizer。
尝试将 sizer = self.GetSizer() 切换为 sizer = self.m_panel71.GetSizer()
