We use RAP for our products and our customers need very good readability of values even when the inputfields are not editable. Unfortunatly the Internet Explorer colors the text of a disabled Combo light-gray, which is quite unreadable on a light background.

RAP resp. QX renders a disabled inputfield with the HTML-Attribute 'disabled' which results in a textcolor as stated. Unfortunatly IE does not allow us to style the foreground-color with CSS.

Styling the Combo with SWT.READONLY results in a rendering as we want it, because then, the html-attribute 'readonly' is set on the inputfield. Again, unfortunatly, there is no 'setEditable' Method for Combo to set the readOnly-State at runtime, so we need to stick with the 'setEnabled' Method.

Reproducible: Always

Steps to Reproduce:
1. Place a Combo in a Container
2. call Combo.setEnabled(false) to disable it
3. Watch the result in IE

CCombo has a possibility to switch the read-only state at runtime (CCombo#setEditable(boolean)). You could give it a try.

hi Ivan,

thank you for your reply. I tried using a CCombo as you suggested.

Setting the CCombo to not editable though has the effect, that only the textinput-field is not editable. The choicelist including the arrow-button stays active. Setting both, enabled and editable, to false leads to the same effect as it is with Combo.

CCombo unfortunatly is not helping here :-(

It's possible the change the Combo foreground color when it is disabled by theming:
Combo:disabled,
Combo[BORDER]:disabled {
  color: red;
}
Tested in Firefox, Chrome, IE9 and IE10. Doesn't work in IE8 and Opera only. We could consider this as a bug in IE8 and Opera. Tim, can we workaround this behavior somehow?

This issue does not exist in Opera 21. Still reproducible only in IE8 with RAP 2.3M3.

This seems to be a known weird behavior in IE8:

The IE7/8 support is discontinued in RAP 3.0. Close as WONTFIX.
