Hello jahlxx,

 

It seems that ExtJS used to have an issue with zoom on mobile on older versions than 5.5. (see https://www.sencha.com/forum/showthread.php?287219)
I don't know if version 4.2 (as embedded in uniGUI) contains this bug.

 

Anyway, you can take a look at these solutions (which depend on your mobile OS) :

 

 

 

For iOS and Android: try to customize the "content" meta in your head section (meta name="viewport" content="...").  Basically, remove "minimum-scale", "maximum-scale" and "user-scalable", just keep this content :

<meta name="viewport" content="width=device-width, initial-scale=1.0">

For Windows devices, you have to check your CSS, the prefixed CSS rule "@-ms-viewport" must not contain a "zoom" property :

@-ms-viewport { width: device-width; }

I guess that you can apply your own Meta or CSS with "CustomMeta" and "CustomCSS" properties of ServerModule, but Farshad or Delphi Developer will be more accurate than me!

Ok.

 

With this:

 

<meta name="viewport" content="width=device-width, initial-scale=1.0">

 

I can do zoom in, but not zoom out. maybe defining minimum scale?

[ZigZig]

maybe defining minimum scale?

 

Maybe! Could you please test that property and tell us if it works?

[jahlxx]

tested. and don't work.

Hi.

 

I'm still fighting with this, playing with scrollboxes, and so.

 

Is there a posibility of define the initialzomm of mainform? I think that if I can do zoom in, but not zoom out, it could be a good idea, detect the device from I'm executinng the app, and if this device is a cell phone, rededefine the initial zoom, and show the app in a small size, but can do zoom in.

 

What do you think?

 

Is possible?

 

How?

 

Thanks.
