Subject: QQuickLineControl more robust on input method & selection state
X-Git-Url: http://git.silmor.de/gitweb/?a=commitdiff_plain;h=0332e605f916ff67ce579172e857e457e8ea3e41;p=konrad%2Fqtdeclarative.git

QQuickLineControl more robust on input method & selection state

Input method event having replacement information out of bounds
left the controller in selection state when it shouldn't be.
Also now more liberal on accepted events. We cannot detect if input
method is confused for replacement inside boundaries, but going beyond
the end is more likely to be meant to replace until the end than to
leave previous text in addition to the new one.
