It looks like there's currently no quick way. Maybe the "package view" would work better for you - right click on the project -> select "folder view" -> select "package".
If you have the pro version of slickedit you could load the following macros to get commands "collapse all" and "expand all". It's also possible to modify the right click menus in the project tool-window to add "expand children" and "collapse children".
Did you know there's a command in the right click (context) menu of an edit window to show the current file in the projects toolwindow (Show File In Projects Tool Window). The open toolwindow also allows you to synch the current directory with the current edit buffer. A quick way to open a file is to use the "e" command on the command line followed by the name of the file - slick will give you choices. The open toolwindow allows you to type any part of the filename and it will list matching files in all sub-folders.
#include "slick.sh"
_command void collapse_all_projects_tw() name_info(',')
{
// bring up the projects toolbar
activate_projects();
// find our projects tree
tree := _tbGetActiveProjectsTreeWid();
if (tree > 0) {
tree._TreeCollapseAll(true);
}
}
_command void expand_all_projects_tw() name_info(',')
{
// bring up the projects toolbar
activate_projects();
// find our projects tree
tree := _tbGetActiveProjectsTreeWid();
if (tree > 0) {
tree._TreeExpandAll(true);
}
}
