Seems to work fine here, can anybody else confirm ?

Using the mouse wheel you can't reach the last empty line it adds.

[gurj]

Before 2010（？）, there is this problem.I remember that about.

Confirmed here: Using 6.01, I can mouse scroll wheel down to the bottom of the gadget. With 6.02, I can't.

However, it works with 6.02 if you add this line after the EditorGadget() command:

Code: Select all

SendMessage_(GadgetID(0), #EM_SETTEXTMODE, #TM_RICHTEXT, 0)

So probably another winapi oddity

[netmaestro]

Not sure I agree with the winapi idea. The reason is if I do the same thing on the wordpad app that ships with windows, put in 20 lines or so followed by some blank lines, shorten the window up so only ten or so lines show, the mousewheel will scroll the gadget all the way down to show the last blank line. Both are using the RICHEDIT50W control. I lean towards a vote for a bug in PB (for now).

[Fred]

Notepad uses the RTF mode AFAIK, that's why it behaves like that. You could try with a pure winapi control but we don't hook any mouse related events so I don't think it will on PB side this time

[gurj]

@BarryG,ok! thanks!

[gurj]

@Fred,why only 6.02 not?

[Fred]

It's because we switched the EditorGadget to plain mode by default (instead of RTF) as it raised unexpected issues. To get 6.01 behaviour, just set back the RTF mode with SendMessage()

[gurj]

but,now,why pb6.02 cannot use #TM_PLAINTEXT? why 6.01 can?
