java - Root immediate child nodes icons not visible when hiding root -


i have jtree structure shown below. have icons appear whenever node has child nodes, working properly.

my problem need hide root node. when hide root node, icons maintop1 , maintop2 nodes not displayed, though have children. hide root node i'm using "setrootvisible(false)".

also when root node hidden, icons topic1 , topic nodes displayed properly.

anyone knows how display icons maintop1 , maintop2 when root hidden? in advance.

below tree structure:

root     maintop1         topic1             subtopic1             subtopic2     maintop2         topic2             subtopic1

jtree#setshowsroothandles(boolean newvalue) controls state of handles root elements.

normally, false. try changing true

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
