以下代码生成一个带有灰色渐变条的窗口。
import wx
class GradientFrame(wx.Frame):
def __init__(self, parent, title):
wx.Frame.__init__(self, parent, -1, title)
self.Bind(wx.EVT_PAINT, self.OnPaint)
self.Bind(wx.EVT_ERASE_BACKGROUND, lambda event: None)
self.Bind(wx.EVT_SIZE, self.OnSize)
self.Center()
self.Show()
def OnSize(self, event):
event.Skip()
self.Refresh()
def OnPaint(self, event):
dc = wx.BufferedPaintDC(self)
rect = self.GetClientRect()
dc.SetBackground(wx.Brush("white"))
dc.Clear()
rect.SetHeight(30)
dc.GradientFillLinear(rect, '#fbfbfb', '#efefef', wx.SOUTH)
rect.SetTop(30)
rect.SetHeight(2)
dc.GradientFillLinear(rect, '#dbdbdb', '#c1c1c1', wx.SOUTH)
app = wx.App(0)
frame = GradientFrame(None, 'Test')
app.MainLoop()
我想添加像以下屏幕截图那样的按钮,允许访问GUI的不同页面 / 面板(每个都包含自己的小部件,等)
的优秀框架是什么:这些按钮是在OnPaint
手动创建的(这可能是非常“低级”)还是其他地方?是否有现成的方式来使用链接到不同页面的按钮?
答案 0 :(得分:2)
没有用于创建自定义小部件的良好框架。但是,有一些很好的食谱:
这两个链接应该让你入门。您还可以查看GenericButton,AquaButton或PlateButton的来源以获取更多想法。
或者,您也可以创建一个特定尺寸的面板,然后将一些自定义按钮或常规按钮放在其上。
以下是一个如何使用PlateButtons的示例:
import wx
import wx.lib.platebtn as platebtn
class GradientFrame(wx.Frame):
def __init__(self, parent, title):
wx.Frame.__init__(self, parent, -1, title)
self.panel = wx.Panel(self)
self.panel.Bind(wx.EVT_PAINT, self.OnPaint)
self.panel.Bind(wx.EVT_ERASE_BACKGROUND, lambda event: None)
self.panel.Bind(wx.EVT_SIZE, self.OnSize)
# add plate buttons
top_sizer = wx.BoxSizer(wx.VERTICAL)
btn_sizer = wx.BoxSizer(wx.HORIZONTAL)
labels = ["Morceaux", "Albums", "Artistes", "Genres"]
style = platebtn.PB_STYLE_GRADIENT
for label in labels:
btn = platebtn.PlateButton(self.panel, label=label, style=style)
btn.SetPressColor(wx.Colour(208,208,208))
btn_sizer.Add(btn, 0, wx.RIGHT|wx.LEFT|wx.CENTER, 5)
top_sizer.Add(btn_sizer, 0, wx.ALL|wx.CENTER, 5)
top_sizer.Add((1,1), 1, wx.EXPAND)
self.panel.SetSizer(top_sizer)
self.Center()
self.Show()
def OnSize(self, event):
event.Skip()
self.Refresh()
def OnPaint(self, event):
dc = wx.BufferedPaintDC(self.panel)
rect = self.panel.GetClientRect()
dc.SetBackground(wx.Brush("white"))
dc.Clear()
rect.SetHeight(30)
dc.GradientFillLinear(rect, '#fbfbfb', '#efefef', wx.SOUTH)
rect.SetTop(30)
rect.SetHeight(2)
dc.GradientFillLinear(rect, '#dbdbdb', '#c1c1c1', wx.SOUTH)
app = wx.App(0)
frame = GradientFrame(None, 'Test')
app.MainLoop()
