Hello, everyone, I am currently doing QTreeView, through the custom Style Sheets to customize the appearance, want to distinguish the root node and leaf nodes, but in Style Sheets is not found in the corresponding methods, I look at the Qt attribute selectors may be a breakthrough, but there's no way of thinking,

Achieve the result of this now:


If able to distinguish between root node and leaf nodes, then I can to change the picture of the root node with no points, +.
QSS code is as follows:

 
QTreeView: : branch: from - siblings:! Adjoins - item {
Margin - left: 6 px; 
Border - image: url (:/branch - vline PNG); 
} 

Branch: QTreeView...! From - the children: from - siblings: adjoins - item {
Image: url (/branch - more. SVG); 
Margin - left: - 45 px; 
Background - image: url (:/branch - single SVG); 
Background - position: right; 
Background - repeat: no - repeat; 
} 

Branch: QTreeView...! From the children:! From the - siblings: adjoins - item {
Border - image: none; 
Image: url (:/branch - end. SVG); 
Margin - left: - 45 px; 
Background - image: url (:/branch - single SVG); 
Background - position: right; 
Background - repeat: no - repeat; 
} 

QTreeView: : branch: from - children: adjoins - item: open {
Border - image: none; 
Image: url (/branch - more. SVG); 
Margin - left: - 45 px; 
Background - image: url (/branch - open. SVG); 
Background - position: right; 
Background - repeat: no - repeat; 
} 

QTreeView: : branch: from - children: adjoins - item: closed {
Border - image: none; 
Image: url (/branch - more. SVG); 
Margin - left: - 45 px; 
Background - image: url (/branch - closed. SVG); 
Background - position: right; 
Background - repeat: no - repeat; 
} 

QTreeView: : branch: from - children: adjoins - item: open: first {
Background - image: url (/branch - root - open. SVG); 
} 

QTreeView: : branch: from - children: adjoins - item: closed: first {
Background - image: url (/branch - root - closed. SVG); 
}
