 Posted: Tue Apr 01, 2008 1:48 am Post subject: Add ToolTips to controls. |
 |
|
Just a simple add on to allow tooltips to be added to controls without having to monitor the wm_mousemove messages.
| Code: |
; ### Example Code #####
Gui,Add,Button,hwndbutton1 Gbut1,Test Button 1
Gui,Add,Button,hwndbutton2,Test Button 2
Gui,Add,Button,hwndbutton3,Test Button 3
AddTooltip(button1,"Press me to change my tooltip")
AddTooltip(button2," Another Test Tooltip")
AddTooltip(button3,"A Multiline`nTest Tooltip")
Gui,show,,Test Gui
Return
But1:
AddTooltip(button1,"Wasn't that easy `;)",1)
REturn
GuiClose:
Guiescape:
Exitapp
; ### End Example Code #####
AddToolTip(con,text,Modify = 0){
Static TThwnd,GuiHwnd
If (!TThwnd){
Gui,+LastFound
GuiHwnd:=WinExist()
TThwnd:=CreateTooltipControl(GuiHwnd)
}
Varsetcapacity(TInfo,44,0)
Numput(44,TInfo)
Numput(1|16,TInfo,4)
Numput(GuiHwnd,TInfo,8)
Numput(con,TInfo,12)
Numput(&text,TInfo,36)
Detecthiddenwindows,on
If (Modify){
SendMessage,1036,0,&TInfo,,ahk_id %TThwnd%
}
Else {
Sendmessage,1028,0,&TInfo,,ahk_id %TThwnd%
SendMessage,1048,0,300,,ahk_id %TThwnd%
}
}
CreateTooltipControl(hwind){
Ret:=DllCall("CreateWindowEx"
,"Uint",0
,"Str","TOOLTIPS_CLASS32"
,"Uint",0
,"Uint",2147483648 | 3
,"Uint",-2147483648
,"Uint",-2147483648
,"Uint",-2147483648
,"Uint",-2147483648
,"Uint",hwind
,"Uint",0
,"Uint",0
,"Uint",0)
Return Ret
} |
You need to send the function the hwnd of the control, and the text you want it to say. If you are changing a tooltip, then specify a 1 for the last parameter.
As always, comments, bugs, questions, suggestions etc.... all welcome.

| Nice! Could you put in some comments about the names of the messages and the magic parameters? It would make changing the code easier. |

Yes, its nice and could be pretty helpful.
But at the moment it seems to work only with buttons.
Can the script also work with other controls? |

So far i've tested on Tabs,Edits,buttons,checkboxes and text (static).
Only text failed so far, and im struggling to find anydocumentation in MSDN to say it doesnt work with any type.

Of course it works for static controls. Just add a "null" g-label:
| Code: | Gui,Add,TEXT,hwndTEXT1 gNULL,Testing for static.
...
...
NULL:
Return

Wonderful!
I tested it with gLabel, but there was a misspelling....sorry.
I've a question to the dllcall of CreateWindowEx. After seaching I found some VBA code for ToolTip. From that I made the following:
| Code: | CreateTooltipControl(hwind){
Ret:=DllCall("CreateWindowEx"
,"Uint",0
,"Str","TOOLTIPS_CLASS32"
,"Str",""
,"Uint",0|3
,"Uint",0
,"Uint",0
,"Uint",0
,"Uint",0
,"Uint",hwind
,"Uint",0
,"Uint",0
,"Uint",0)
Return Ret
} |
This also works. My Question: Is there a reason for the other function call?
And as a second: where does the Msg numbers come from? In google I found some code with this numbers, that have to do with slider range and toolbarbuttons. |

When a Tooltip is changed from another Window, the ToolTip is not updated.
Changing | Code: | If (Modify){
SendMessage,1036,0,&TInfo,,ahk_id %TThwnd%
}
Else {
Sendmessage,1028,0,&TInfo,,ahk_id %TThwnd%
SendMessage,1048,0,300,,ahk_id %TThwnd%
} |
to | Code: | If (Modify)
SendMessage,1036,0,&TInfo,,ahk_id %TThwnd%
Else
SendMessage, 1028,0,&TInfo,,ahk_id %TThwnd%
SendMessage,1048,0,300,,ahk_id %TThwnd% |
helps. |

The first function call(createwindow) creates a tooltip control, this is required to store/create/show/hide the tool tips, this is only needed once. We then add the tool tips to the control, they can be attached to either controls or areas, at present only controls are supported.
The messages are
TTM_ADDTOOL = 1028 (used to add a tool, and assign it to a control)
TTM_UPDATETIPTEXT = 1036 (used to adjust the text of a tip)
TTM_SETMAXTIPWIDTH = 1048 (This one allows the use of multiline tooltips.)

I am unable to replicate this, they change fine in all my tests. And unless I am missing something I can't see how the changes would fix it.
All you are doing is sending the maxwidth message everytime, instead of only during an add, I'll take a proper look later.

In the first part of my question I wanted to know, if you can explain the found
differences like
| Quote: | ,"Str","TOOLTIPS_CLASS32"
,"Str",""
,"Uint",0|3
,"Uint",0 |
| Quote: | ,"Str","TOOLTIPS_CLASS32"
,"Uint",0
,"Uint",2147483648 | 3 |
especially I want to know if my found version is wrong, or if both are right.
I tried a short script to test my update-problem. You're right, it works well.
I have scripted a longer program where I can change the language on the fly over two windows. There it works only with the above changes. So it seems to be a problem with my program. [EDIT] I found the problem and fixed it. I had a try with onmessage before. I deleted this and now your code worked as it should.
Thanks for your answer and this wonderful function!!

The number in mine stands for WS_POPUP which is one of the window styles that MSDN has in its example.
As to the str and Uint differences. Officially it should be an str, but as I am sending null I believe this does not matter. (Although I could be mistaken.)
