当textctrl改变时wxpython运行
我正在 wxpython 中制作一个简单的文本编辑器。我希望它能够编辑 python 等代码,因此我希望它以与 IDLE 或 Notepad++ 类似的方式突出显示文本。我知道如何突出显示它,但我想要运行它的最佳方式。我不知道是否可能,但我真正想要的是每当按下某个键时就运行,而不是循环检查是否按下,以便节省处理。
import wx
class MainWindow(wx.Frame):
def __init__(self, parent, title):
wx.Frame.__init__(self, parent, title=title, size=(500,600))
style = wx.TE_MULTILINE|wx.BORDER_SUNKEN|wx.TE_RICH2
self.status_area = wx.TextCtrl(self, -1,
pos=(10, 270),style=style,
size=(380,150))
self.status_area.AppendText("Type in your wonderfull code here.")
fg = wx.Colour(200,80,100)
at = wx.TextAttr(fg)
self.status_area.SetStyle(3, 5, at)
self.CreateStatusBar() # A Statusbar in the bottom of the window
# Setting up the menu.
filemenu= wx.Menu()
filemenu.Append(wx.ID_ABOUT, "&About","Use to edit python code")
filemenu.AppendSeparator()
filemenu.Append(wx.ID_EXIT,"&Exit"," Terminate the program")
# Creating the menubar.
menuBar = wx.MenuBar()
menuBar.Append(filemenu,"&File") # Adding the "filemenu" to the MenuBar
self.SetMenuBar(menuBar) # Adding the MenuBar to the Frame content.
self.Show(True)
app = wx.App(False)
frame = MainWindow(None, "Python Coder")
app.MainLoop()
如果需要循环,最好的方法是什么让它循环,使用 while 循环,或者
def Loop():
<code>
Loop()
添加绑定的我的新代码:
import wx
class MainWindow(wx.Frame):
def __init__(self, parent, title):
wx.Frame.__init__(self, parent, title=title, size=(500,600))
style = wx.TE_MULTILINE|wx.BORDER_SUNKEN|wx.TE_RICH2
self.status_area = wx.TextCtrl(self, -1,
pos=(10, 270),style=style,
size=(380,150))
#settup the syntax highlighting to run on a key press
self.Bind(wx.EVT_CHAR, self.onKeyPress, self.status_area)
self.status_area.AppendText("Type in your wonderfull code here.")
fg = wx.Colour(200,80,100)
at = wx.TextAttr(fg)
self.status_area.SetStyle(3, 5, at)
self.CreateStatusBar() # A Statusbar in the bottom of the window
# Setting up the menu.
filemenu= wx.Menu()
filemenu.Append(wx.ID_ABOUT, "&About","Use to edit python code")
filemenu.AppendSeparator()
filemenu.Append(wx.ID_EXIT,"&Exit"," Terminate the program")
# Creating the menubar.
menuBar = wx.MenuBar()
menuBar.Append(filemenu,"&File") # Adding the "filemenu" to the MenuBar
self.SetMenuBar(menuBar) # Adding the MenuBar to the Frame content.
self.Show(True)
def onKeyPress (self, event):
print "KEY PRESSED"
kc = event.GetKeyCode()
if kc == WXK_SPACE or kc == WXK_RETURN:
Line = self.status_area.GetValue()
print Line
app = wx.App(False)
frame = MainWindow(None, "Python Coder")
app.MainLoop()
I am making a simple text editor in wxpython. I would like it to be able to edit code such as python, and as such I would like to have it highlight the text in a similar manner to IDLE or Notepad++. I know how I would highlight it, but I would like the best way of running it. I don't know if it is possible but what I would really like is to run whenever a key is pressed, and not on a loop checking if it is pressed, so as to save on processing.
import wx
class MainWindow(wx.Frame):
def __init__(self, parent, title):
wx.Frame.__init__(self, parent, title=title, size=(500,600))
style = wx.TE_MULTILINE|wx.BORDER_SUNKEN|wx.TE_RICH2
self.status_area = wx.TextCtrl(self, -1,
pos=(10, 270),style=style,
size=(380,150))
self.status_area.AppendText("Type in your wonderfull code here.")
fg = wx.Colour(200,80,100)
at = wx.TextAttr(fg)
self.status_area.SetStyle(3, 5, at)
self.CreateStatusBar() # A Statusbar in the bottom of the window
# Setting up the menu.
filemenu= wx.Menu()
filemenu.Append(wx.ID_ABOUT, "&About","Use to edit python code")
filemenu.AppendSeparator()
filemenu.Append(wx.ID_EXIT,"&Exit"," Terminate the program")
# Creating the menubar.
menuBar = wx.MenuBar()
menuBar.Append(filemenu,"&File") # Adding the "filemenu" to the MenuBar
self.SetMenuBar(menuBar) # Adding the MenuBar to the Frame content.
self.Show(True)
app = wx.App(False)
frame = MainWindow(None, "Python Coder")
app.MainLoop()
If a loop is needed what would be the best way to make it loop, with a while loop, or a
def Loop():
<code>
Loop()
My new code with the added bind:
import wx
class MainWindow(wx.Frame):
def __init__(self, parent, title):
wx.Frame.__init__(self, parent, title=title, size=(500,600))
style = wx.TE_MULTILINE|wx.BORDER_SUNKEN|wx.TE_RICH2
self.status_area = wx.TextCtrl(self, -1,
pos=(10, 270),style=style,
size=(380,150))
#settup the syntax highlighting to run on a key press
self.Bind(wx.EVT_CHAR, self.onKeyPress, self.status_area)
self.status_area.AppendText("Type in your wonderfull code here.")
fg = wx.Colour(200,80,100)
at = wx.TextAttr(fg)
self.status_area.SetStyle(3, 5, at)
self.CreateStatusBar() # A Statusbar in the bottom of the window
# Setting up the menu.
filemenu= wx.Menu()
filemenu.Append(wx.ID_ABOUT, "&About","Use to edit python code")
filemenu.AppendSeparator()
filemenu.Append(wx.ID_EXIT,"&Exit"," Terminate the program")
# Creating the menubar.
menuBar = wx.MenuBar()
menuBar.Append(filemenu,"&File") # Adding the "filemenu" to the MenuBar
self.SetMenuBar(menuBar) # Adding the MenuBar to the Frame content.
self.Show(True)
def onKeyPress (self, event):
print "KEY PRESSED"
kc = event.GetKeyCode()
if kc == WXK_SPACE or kc == WXK_RETURN:
Line = self.status_area.GetValue()
print Line
app = wx.App(False)
frame = MainWindow(None, "Python Coder")
app.MainLoop()

在您的 MainWindow
__init__
函数中添加此代码,然后在 MainWindow 中定义 onKeyPress
想想看,这可能不是执行代码突出显示的最有效方法。让我查一下这个。但与此同时你可以尝试这个。
编辑:
看看这个 - StyledTextCtrl 。我认为它更符合您的需求。
In your MainWindow
__init__
function add thisthen define onKeyPress in MainWindow
Come to think of it, this might not be the most efficient way of doing code highlighting. Let me look this up. But in the meantime you can try this.
Edit:
Take a look at this - StyledTextCtrl . I think its more along the lines of what you need.
当我遇到同样的问题时,我通过创建自定义事件解决了这个问题。
首先,我创建了 TextCtrl 的子类,因此我在代码中有一个位置可以引发/发布自定义事件:
现在,在我的框架代码中,这是我绑定事件并使用它的片段。
I solved this when I faced the same issue by creating a custom event.
First, I created a subclass of the TextCtrl, so I had a place in code to raise/post the custom event from:
Now, in my frame's code, here is a snippet of me Binding the event, and using it.
