Is there GWT api that will tell me which browser version it detected?
I've found a flaw with IE7's regex handling and need to code around some tricky String.matches() expressions.
You could use GWT deferred binding using replacement and create two implementations of your class in which you use regex.
For example let's assume your class is named Parser
and it contains code for all web browsers except for IE7. Then you can extend Parser
and create ParserIE7
class for IE7. Then in your GWT module config file you can add:
<replace-with class="Parser">
<when-type-is class="Parser"/>
</replace-with>
<replace-with class="ParserIE7">
<when-type-is class="Parser" />
<when-property-is name="user.agent" value="ie7"/>
</replace-with>
Then by calling
Parser parser = GWT.create(Parser.class);
you should have a proper (web browser dependent) implementation of Parser
in parser
variable.
You can find more details here.
