jEdit 4.4.1 Windows nits
Submitted by dirckb on Monday, 25 July, 2011 - 20:09
Switching to jEdit 4.4.1 on Windows 7; so far I'm enjoying jEdit, but are are some minor annoyances:

* using command line to open a file in jEdit will not switch the keyboard focus to jEdit.

Here's a workaround: front.py

#   bring named window to front
import re
import sys
import win32gui

def winEnumHandler(hwnd, match):
    if win32gui.IsWindowVisible(hwnd):
        if match(win32gui.GetWindowText(hwnd)):
            print "found"
            win32gui.SetForegroundWindow(hwnd)
            win32gui.SetFocus(hwnd)

def front(pattern):
    match = re.compile(pattern).match
    win32gui.EnumWindows(winEnumHandler, match)

if __name__ == '__main__':
    front(sys.argv[1])
and j.cmd:
start C:\PROGRA~1\jEdit\jedit.EXE %*
front "jEdit.*"
This helps but doesn't seem to work every time. Probably needs an event flush somewhere.

Another nit:

* jEdit uses alt+ keys (arrow, pgup/pgdown/home/end, etc). I like to use the keypad (w/numlock off) for these keys, but with alt+keypad, Windows insists on adding a Unicode character, even with numlock off.

I've done some googling but haven't found a workaround for this yet. Might have to add alternate mappings for the relevant shortcuts.

Lockups
by dirckb on Thu, 04/08/2011 - 17:35
I've been getting occasional lock-ups where jedit won't respond to the mouse or keyboard, but doesn't seem to be hung in a loop. These may have been caused by the front.py hack. Apparently the win32.SetFocus call isn't necessary, and this call is the suspect for my new problem. Here's the current front.py:
#   bring named window to front
import re
import sys
import win32gui

def winEnumHandler(hwnd, match):
    if win32gui.IsWindowVisible(hwnd):
        if match(win32gui.GetWindowText(hwnd)):
            print "Found:", win32gui.GetWindowText(hwnd)
            win32gui.SetForegroundWindow(hwnd)

def front(pattern):
    win32gui.EnumWindows(winEnumHandler, re.compile(pattern).match)

if __name__ == '__main__':
    front(sys.argv[1])
 
More locking up in Windows 7

OK, even without my silly little front.py hack, the jedit window can get stung. A seemingly consistent case: from the Windows command line (cmd), try to open a '*.py' file that doesn't exist. Switch to the jEdit window and it won't respond to mouse or keyboard. Tried with both the jedit.exe and running the jedit.jar from a java command line.

Maybe this isn't the same lockup from before, although it's the same behavior - this one only happens if the JPyDebug plugin is installed.

The previous lockup seemed a lot more random, and I didn't have JPyDebug installed at the time. Guess I could go to vanilla jEdit and slowly add stuff back in until it breaks.
 
Splash is already disabled

And my focus problems usually occur when switching to an already-running jEdit.

Thanks for the tip, though.
