Keyboard control wx global catch implementation

[INPUTrrr0]

The user always needs to press the "+1 frame" button. It can be very tiring clicking the mouse all the time.
Therefore, I tried to implement some keyboard trigger for the most commonly pressed button. However, in wx, to implement a keyboard trigger, I find the only way is to bind a
b=wx.Button(self,label='Button',pos=(100,100)) b.Bind(wx.EVT_KEY_DOWN, self.onButtonKeyEvent)
This requires the button to be focused. I have tried to bind the keydown event to the wx frame. However, seems like it is not possible. I have looked for many ways to catch keydown event globally but I wasn't able to find a solution. Is there a possible way to catch a keyboard event globally in this tool?
Thanks!

Hi! This issue has been resolved in PR #4.

The solution uses wx.AcceleratorTable to set up global keyboard shortcuts that work without requiring button focus.

Implemented shortcuts:

• ← / → : Previous/Next frame (-1/+1)
• Shift + ← / Shift + → : Previous/Next N frames (-FPI/+FPI)
• S : Select start frame
• E : Select end frame
• Ctrl + S : Save label

The key is using wx.AcceleratorTable with wx.ACCEL_NORMAL and wx.ACCEL_SHIFT flags, then binding the menu events:

accel_entries = [
    (wx.ACCEL_NORMAL, wx.WXK_LEFT, id_prev),
    (wx.ACCEL_NORMAL, wx.WXK_RIGHT, id_next),
    ...
]
accel_table = wx.AcceleratorTable(accel_entries)
self.SetAcceleratorTable(accel_table)

This approach catches key events globally at the frame level, so you don't need to worry about which widget has focus.

Hope this helps! 🐻
