Exploit custom dialog function: searching for help/hints

[Aeris]

I've noticed between lipc commands this interesting one:

com.lab126.pillow customDialog

where Dialog is a writable string. I found then an html file that seems to be inherent to this command:

Filepath: /usr/share/webkit-1.0/pillow/sample_custom_dialog.html

And two javascript files too...

First: /usr/share/webkit-1.0/pillow/javascript/sample_custom_dialog.js:

And second: usr/share/webkit-1.0/pillow/strings/sample_custom_dialog_strings.js

Can somebody help me to exploit this and understand how to invoke properly the lipc command? If possible...

It would be cool to popup custom native dialogs in our programs

Thank you!

Don't know... maybe it could receive some parameters through "interrogatePillow" etc... And also strings doesn't seem to mean always true or false value values

[eureka]

Pure guess, but it works. I didn't look at its internals and don't know anything about possible additional parameters, except dialog's name.

lipc-set-prop com.lab126.pillow customDialog '{"name": "sample_custom_dialog"}'

To hide it:

lipc-set-prop com.lab126.pillow interrogatePillow '{"pillowId": "sample_custom_dialog", "function": "nativeBridge.dismissMe()"}'

(There should be another, official way to close Pillow windows from shell prompt, but it's all I can come to ATM.) I believe, I was wrong. There is no common method to close Pillow windows via LIPC (except nativeBridge.dismissMe function).

I don't know how about PW, but KT's pillow looks for HTML files, dialogs included, also at /usr/local/tests/pillow (tested on 5.3.2.1).

UPD: ha, I've just found my old notes about Pillow regarding customDialog property:

/usr/local/tests/pillow (fallback of /usr/share/webkit-1.0/pillow)

To load stock Pillow scripts from HTML placed in fallback location:
<script src="///usr/share/webkit-1.0/pillow/javascripts/sample_custom_dialog.js">

To show example.html:
lipc-set-prop com.lab126.pillow customDialog '{"name": "example"}'

To show example/index.html
lipc-set-prop com.lab126.pillow customDialog '{"name": "example/index"}'

To set parameters:
lipc-set-prop com.lab126.pillow customDialog '{"name": "sample_custom_dialog", "clientParams": {"dismiss": true}}'

sample_custom_dialog handles dismiss parameter and closes itself on receiving it.

I knew I could count on you, Eureka! Thank you so much! Last command tested and work beautifully

Now I've just to play with it for a while to discover the best way to exploit it.

The simplest one could be to use it in a unconventional manner, i.e. for blocking user input on eips full screen prints (just invoke lipc-set-prop com.lab126.pillow customDialog '{"name": "sample_custom_dialog", "clientParams": {"dismiss": true}}' before and after executing your eips script).

For example in Midori splash animation...

EDIT: It doesn't work well unless you manage to open a very little custom dialog, lets say 1x1 px... otherwise if the user clicks in the popup area it will appear cleaning the eipsed area

Then I'll see how to use it in a proper manner, as custom dialogs displayer

[twobob]

Work fine on PW. just to give feedback.

[Aeris]

The simplest use could be maybe to inject javascript as Eureka did for the battery widget into sample_custom_dialog, overriding the original html test with the one we need. Maybe could be added some buttons too in this way...

Just creating a simple Yes/no statement window would be a nice point to start

I don't know how about PW, but KT's pillow looks for HTML files, dialogs included, also at /usr/local/tests/pillow (tested on 5.3.2.1).

I've tried to copy sample_custom_dialog.html into sample_custom_dialog2.html in that folder but doesn't seems to work on paperwhite (I invoked it with lipc-set-prop com.lab126.pillow customDialog '{"name": "sample_custom_dialog2.html"}')

[eureka]

Pay attention to examples, you did it wrong.

[Aeris]

Ok, I will! I wrote an html where not needed... but I've tried also without .html and still not detected

I'm watching a lot to your examples, this one and battery one... now I'm trying to find a way to set "display:visible" instead of "none" by javascript, to an element without id...

I managed to achive this only by hand, editing the value in the original sample_custom_dialog file... results seem pretty promising:

If well understood maybe this could be used to set up many bash scripts for KUAL

Anyway, if custom dialogs aren't used from any system app, editing this file should be safe too I think

[eureka]

You shouldn't edit this concrete file or use interrogatePillow to get something useful to display with customDialog property.

Pillow concatenates /usr/share/webkit-1.0/pillow/ string with name string and then the result is concatenated again with .html string. Then Pillow tries to load file by resulting path. Do you understand how it works now?

Does

strings /usr/lib/libpillow.so | grep local

command output contain /usr/local/tests/pillow/?

[twobob]

[root@kindle root]# strings /usr/lib/libpillow.so | grep local

setlocale
/usr/local/tests/pillow/
enable-html5-local-storage
localeChange
com.lab126.locale

Aye Captain

[Aeris]

Yes, it does... but I tought it tried to search html in /usr/local/tests/pillow/ when it could not find them in /usr/share/webkit-1.0/pillow/

You shouldn't edit this concrete file or use interrogatePillow to get something useful to display with customDialog property.

Is there any other choice?

[twobob]

possibly stracing it's ACTUAL searched execution pathS would be illuminating?

If it outputs /usr/local/tests/pillow, then it uses it. Probably, for searching of HTML files to display. At least, on KT it does. And yes, Pillow uses this directory as fallback choice. /usr/share/webkit-1.0/pillow/ is the default location.

Yes. On setting customDialog property, put anything you want into name key. What file Pillow will load then?
