Radiobuttons: Updating the particular Image when selecting it

Hi,

I am creating a page with InstallOptions and preview images.
If you select a radiobutton an image should be displayed and if you select another radiobutton another should be displayed.

Here you can see what I want to create:




But at the moment only one image for both is displayed, even if I defined two; So there is no change of the images.

I checked all the InstallOptions examples, but my problem isn't described there.

Greetings, Chieftec

Is there no one who knows an answer 🙁?

Use Notify on the radio buttons. Have three image controls one on top of another with the different images, and set two of them to hidden (with ShowWindow) before showing the page (between InitDialog and Show/Display). Depending on the selected radio button, use ShowWindow to hide all the images and then ShowWindow to show the correct one.

Thank you for your response Afrow UK!
But how to use ShowWindow... Can you give me an example ?

Hi!

You'll find a small example in the manual:



4.9.14.17 ShowWindow

Have a nice day!

See the testnotify.nsi InstallOptions example and to show / hide the control use something like this.

WinMessages.nsh
...
; get status of radio button
ReadINIStr $0 "$PLUGINSDIR\yourpage.ini" "Field x" "State"
StrCmp $0 "1" 0 noshow
; get handle of image control
ReadINIStr $1 "$PLUGINSDIR\yourpage.ini" "Field x" "HWND"
ShowWindow $1 ${SW_SHOW}
noshow:
...

Thank you {_trueparuex^}

I tried it like you said, but it hides the buttons and not the image...
Any Idea?

Oops. Use the image control field number instead of radio button field number.

...
; get status of radio button
ReadINIStr $0 "$PLUGINSDIR\yourpage.ini" "Field x" "State"
StrCmp $0 "1" 0 noshow
; get handle of image control
ReadINIStr $1 "$PLUGINSDIR\yourpage.ini" "Field y" "HWND"
ShowWindow $1 ${SW_SHOW}
noshow:
...

Actually now when I think, there is a lot better way to do this. The radio button status is either 1 or 0 and the ShowWindow will hide the control with show_state 0 and show the control with show_state 1. So you should be able to use code like this...

; get the state of radio button 1
ReadINIStr $0 "$PLUGINSDIR\yourpage.ini" "Field x1" "State"

; get the handle of image control 1
ReadINIStr $1 "$PLUGINSDIR\yourpage.ini" "Field y1" "HWND"

; simply pass the radio button status as show_state for the image control.
ShowWindow $1 $0

; do the same thing for every radio button / image control

... I made a small example.

Thank your very much! It works fine 🙂
