ComboBox include strings with "|" and "||

[danielo515]

Hello,

I was wondering if there is a way to include "options" in a combo-box that includes "|" and "||" as part of the string. Any way to escape them or any know workaround?

Regards

Use http://ahkscript.org/docs/commands/Gui.htm#Options "Delimiter: Specifies that the window should use a field separator other than pipe (|)"

does the backtick ` not work as escape char? as in `| ?

Use http://ahkscript.org/docs/commands/Gui.htm#Options "Delimiter: Specifies that the window should use a field separator other than pipe (|)"

The problem using that option is that it just moves the same problem to another character. I want to allow the user to set any string to be used into the combobox, so they can end using the "new" Delimiter character at some point.

Hello.

Can't you use the following?

comboBoxList := RegExReplace(list, anySignSeperator, "|")

Hello.

Sorry, I don't understand your point at all.

The problem is that the end user can include any string. So what I have to do is to escape the special characters the user could input, not the other way round.

[AndreySibiryakov]

Ok, I understand it. But will the end user edit the code?
If not, you can use RegExReplace command to find and replace any character that user will use.
For example, "space" is used or "tab".
And the end user can enter this sign in a window from where a variable "anySignCharacter" can obtained.

You can use a character that the user is unlikely (or unable) to enter, such as an ASCII control character. If you're specifically targetting Unicode versions of AutoHotkey, you can use a non-character code point such as Chr(0xFFFF).

Alternatively, you can send ComboBox messages to the control instead of using the Gui commands.

Hello Lexikos. I like your idea of using an ASCII control character, but I'm failing implementing it. Here is how I did it:

Code: Select all

Delim:=Chr(0xFFFF)
gui, mainGui:+Delimiter%Delim%
[.....]
Gui, Add, ComboBox , vTemplate w%templatewidth%, % functionthatjoinsteverything(Delim)

Everything is appearing in the same line.

You might want to use CB_AddItem().

Hello Lexikos. I end using `a as a separator. It is working for now, but I'm facing a small problem: I'm not able to set a selected item. This is done using "||" normally. What I tried is to use the delimiter twice, but it does not work. Any idea why?

Code: Select all

delim=`a
list:= "hello" . delim . delim . "dude" . delim . "How are you"

Hello Just me. I thought about using it, but as I have read it has some delay after each addition. It also makes things a bit, more complicated because currently the items are stored on an object, and I just call the join method of that object with the correct delimiter. Anyway, if I use the CB_Additem approach, how do you set a default selected item?

... ,but as I have read it has some delay after each addition.

Where did you read it?

... , and I just call the join method of that object with the correct delimiter.

Instead of joining them into a string you could add them directly.

CB_SelectItem()

[lexikos]

CB_AddItem just sends a CB_ADDSTRING message. If that has a delay, then so must the GUI commands, because they do exactly the same thing.

I like your idea of using an ASCII control character, but I'm failing implementing it.

Funny. Chr(0xFFFF) is not ASCII, but Unicode.

Everything is appearing in the same line.

There are a few possibilities:

1. You've applied +Delimiter to the wrong GUI.
2. Your function is using the wrong delimiter.
3. You're using an ANSI version of AutoHotkey, where Chr(0xFFFF) returns "".

I end using `a as a separator. It is working for now, but I'm facing a small problem: I'm not able to set a selected item.

It works just fine for me, just as you wrote it.

Code: Select all

delim=`a
list:= "hello" . delim . delim . "dude" . delim . "How are you"

Gui +Delimiter%delim%
Gui Add, ComboBox, , %list%
Gui Show
