Need Help on Buttons in custom pages

[gugo46]

Hi all,

I am as new as you can get to NSIS, so excuse my ignorance.

I have created a custom page with a button. I want to call a function when that button is clicked. The function, in turn, will run some commands based on selections made on the custom page.

What works:
1. got a page with 2 radio buttons, text field and Add button
2. i read the values of the fields in my custom page function

Need help:
1. how to call a function from my button, yet remain on the same page
2. the function being called needs to use values read in the custom page function

Is this possible? and if yes, how would I do it?

Any help is GREATLY appreciated.

Use Abort to stay on the current page.

You can store values in variables or on the stack.

Thanks for a quick response....

But how do I call a function from my button?

I have searched the forum and the docs, all I could find was that I can put a command that can be executed with Exec in the state of the button, and clicking the button will Exec that code.

What I need is to click the button and call a method in my script.

Thanks again.

See the InstallOptions documentation and examples about the NOTIFY flag.

Let me check that out....

Great !!!! Thanks, it works, BUT I am encountering another issue: can't get out of the window even if I click close. Here is my code:

Page custom AddUserPage test
.
.
Function AddUserPage ;FunctionName defined with Page command
!insertmacro MUI_HEADER_TEXT "$(TEXT_IO_TITLE)" "$(TEXT_IO_SUBTITLE)"
!insertmacro MUI_INSTALLOPTIONS_DISPLAY "sshUser.ini"

!insertmacro MUI_INSTALLOPTIONS_READ $domain_radio "sshUser.ini" "Field 2" "State"
!insertmacro MUI_INSTALLOPTIONS_READ $local_radio "sshUser.ini" "Field 3" "State"
!insertmacro MUI_INSTALLOPTIONS_READ $user_text "sshUser.ini" "Field 4" "State"

FunctionEnd


Function test
MessageBox MB_OK "add clicked"
Abort
FunctionEnd

I know there has to be a way to close this, my guess would be an error/completion code in the stack?!?! But how would I get it, what do I compare it too? Just need close button to close without calling test again.

Can't thank enough the people responding...

[Joost Verburg]

You should read the status from the INI file, see docs.

[gugo46]

I appologize if it sounds like I don't want to do searching myself, its definetly not the case. I just can not find it in docs or the forum post related to my question.

Dear Joost, after reading the forum for about 5 continous hours I see that your contribution to both the forum and development is quite large.

I would greatly appreciate a pointer to an example or maybe the section in the docs (a link) to solve my problem

Again, thanks for taking the time to answer my questions

If you put only the Abort command inside a leave_function, you won't ever close the program by normal ways. You have to give it some conditions to don't execute the Abort command. You can use StrCmp for comparing strings.

Ok, this is the first step, now you have to have a string to compare with. This can be:

!insertmacro MUI_INSTALLOPTIONS_READ $0 "sshUser.ini" "Settings" "State"

Where the result will be a control number if you selected one, or an empty string if not.

The result code will be as this below:

code:
Function test



  !insertmacro MUI_INSTALLOPTIONS_READ $0 "sshUser.ini" "Settings" "State"

  StrCmp $0 2 +3

  StrCmp $0 3 +2

  StrCmp $0 4 0 +2

    Abort



FunctionEnd

Try it and say if it worked.

Hi all,

1. Thanks a whole lot for the response. REALLY REALLY appreciate it.
2. What you are suggesting is very clear to me. Here is my problem:
I have 3 buttons on the screen, Cancel, Close, Add User (custom page button). Cancel works fine, does what is expected. Add User also behaves normally. Close calls the same method as Add User (I am using notify flag), but in the method I would like to be able to know that the method was called as a result of Close button being clicked not Add User. Is there a way to do that?

So I still have a problem.....

Thanks for your responses.

[deguix]

Instead of using !insertmacro MUI_INSTALLOPTIONS_DISPLAY you can use !insertmacro MUI_INSTALLOPTIONS_DISPLAY_RETURN and pop the return value. The value can be one of these:

success - The user has pressed the Next button

back - The user has pressed the Back button

cancel - The user has pressed the Cancel button

error - An error has occurred, the dialog cannot be displayed.

Thanks for the info, I have tried it with interesting results...still does not work.

How can I attach my file? I appologize in advance for pasting the code...

Please take a look, maybe I am doing something exceptionally stupid.

Ahh, so "Close" button is the "Next" button...

Replace (Field number of "Add User" button) as it says.

code:
c2:

MessageBox MB_OK "Closed"

goto done



!insertmacro MUI_INSTALLOPTIONS_READ $0 "sshUser.ini" "Settings" "State"



StrCmp $0 '(Field number of "Add User" button)' 0 EndAddUser



  MessageBox MB_OK '"Add User" button executed!'



EndAddUser:
