我应该如何添加按钮快捷键/加速器?

self.newItemButton = wx.Button(self.mainPanel, label='Scan &New Item')

似乎无法在我的平台上运行。

示例代码:

import wx
class SpamButton(wx.Frame):
    def __init__(self, parent, title):
        wx.Frame.__init__(self, parent, title=title)
        self.mainPanel = wx.Panel(self)
        self.thisSpamButton()
        self.Show()

    def thisSpamButton(self):
            self.sizer = wx.BoxSizer(wx.VERTICAL)
            #---------------------------------------------
            # So the letter 's' should be underlined right?       | Here it is
            #-----------------------------------------------------v
            self.newItemButton = wx.Button(self.mainPanel, label='&spam')
            self.sizer.Add(self.newItemButton, 0, wx.ALL, 2)
            self.mainPanel.Layout()

def main():
    app = wx.App(False)
    MainFrame = SpamButton(None, 'This Button Short Cut is weird')
    app.MainLoop()

if __name__ == '__main__':
    main()

结果:

Shouldn't the S be underlined?

更新

直到现在,我才真正尝试热键,因为我并不是很好奇。

好的,所以当在这个例子中按alt+hot_key为&垃圾邮件......它可以工作!

然而

热键字母最初没有加下划线。

下划线仅在按下alt时呈现。 :(

答案 0 :(得分:0)

正如@RobinDunn所说,这是一个GTK配置。

基本上将gtk-auto-mnemonics从0更改为1.

由于我使用的是XFCE4,因此我在GTK2中启用了一个特定主题的助记符:

enter image description here

#xfconf-query -c xsettings -p /Net/ThemeName

#grab the current style/theme name
VAR1=$(gconftool-2 --get /desktop/gnome/interface/gtk_theme)
# change to that theme directory
cd /usr/share/themes/$VAR1/gtk-2.0
# replace gtk-auto-mnemonics = 0 with 'gtk-auto-mnemonics=1# = 0'
sudo sed -i 's/gtk-auto-mnemonics/gtk-auto-mnemonics=1#/g' gtkrc
# change the theme to something else ... (Clearlooks, Ambiance, some_theme)
xfconf-query -c xsettings -p /Net/ThemeName -s Default
xfconf-query -c xsettings -p /Net/ThemeName -s $VAR1
#gconftool-2 --type=string -s /desktop/gnome/interface/gtk_theme ????

虽然它们可以正常工作,但按下alt可以提前了解它,而无需按下额外的按钮,其中“丑陋”按钮有加速器。

或者在GTK3中将gtk-auto-mnemonics从0更改为1:

/usr/share/themes/CURRENT_THEME_NAME/gtk-3.0/settings.ini

无需按下alt即可获得结果:
