I have a fall tree with output shown in picture below.In BorderPane "Center" a SplitPane is used to split the view. I want to assign the properties/explorer view to the tree branches & leafs, so that each branch and leaf should have its own properties/explorer view.
My question is this how can i assign this particular split's right side view shown in picture to branch "module" only, and what would be changes if user want this view to be assigned to any leaf. if user click on other branches or leaf this view/properties should not appear. if you need i can provide my sample code,its simple editable tree-view.
i tried but failed. Please
thank you

I'd like to make an NSTableView highlight its selected rows as if one was right-clicked.
When a selected row is right-clicked (and if the table view implements a menu), the view draws a rectangle at the perimeter of each block of selected rows. This is the default behaviour. See below:
I want the table to do that outside of the context of a right-click. FYI, this is to implement a custom dragging Destination Feedback Style to make clear that some action will be applied on the selected rows.
I can programmatically select rows, but not make them highlight in this way.
Still, Appkit must have some method for that since it does it upon right-click.
I could find a solution involving subclassing NSTableView or NSTableRowView, but there may be a simple solution.
Thanks.
Hello everyone.
I have a tree of items as shown on image above (Items tree).
I need to display this tree in a way that is shown on an image (Views).
It has two views, Tree View and List view. Tree view should display the whole tree of items, and list view should display properties for a selected item in a tree view. (On an image it displays properties for a cat item)
The way it is implemented right now is displayed at "Current implementation" part of an image. TreeModel contains item tree, and when you click on an item in a TreeView, current item is sent to a ListModel to display it's properties.
The issue thagt i encounter here is that in both views items are editable. In a tree view you can edit item's names, and this change should appear in a list view as well. The same goes for opposite direction. Changing name of a Cat item should reflect on a treeView cat item.
Since it is two different models, the change is made only when you hover over another view.
What i currently did is for a changed item in one of views, i search for a item in a another view via QModelIndex::match() and then just update that part of a view via emit dataChanged(). I am not sure this a good way. So if maybe you can give me some ideas on how this can be done better.
Thank you.
You should have only one model. The QAbstractItemView::setRootIndex method is all you need: you can set the current item in the tree as the root for the table view. Alternatively, you could use a proxy viewmodel to adapt the data for display in a particular form.
I have created a ASP.NET *TreeView* and binded this TreeView from a dataset.
I want to show the content of tree view in a popup on mouseover on tree view nodes.
I have some description for each node in the dataset.
How to show them in a pop on mouse over?
The pop up has to pull its contents from the dataset.
Its not just thro node.tooltip="sometext".
Is this possible?
I have an AdvancedDataGrid that I populate with HierachialData from XML. I've enabled drag and drop of the children nodes, but want to prevent a child node from being dropped outside of a branch. A child must always be in a branch.
How can I test if the dropped node is outside of a branch?
I managed to solve this using the dragComplete event where I check for any nodes that should be in a branch and copy the node and append it to the last found branch node and delete the dragged one.
If the user drags the leaf to the top of the tree it appends it to the first branch node. This also works well with being able to drag and drop leafs to closed branches.
Is there a way to move/re-parent nodes or am I limited to append a copy/delete old node?
label1

|*label2
|*label3
|___label4
|___label5
I want a tree in this structure, having line between the nodes, also, instead of Open and Close Folders, I have added my own graphic there with label. I did by extending TreeItemRenderer Class. Now, I if iam dragging and dropping a child node ex:label5, and try i drop it above label1 here, it is getting dropped there. i.e.,it is becoming like
label5 ----------> This should not happen.Child should be restricted from being added
label1 above parent.

|_*label3
|___label4
I need to restrict the same. Kindly help me regarding the same.
You can implement custom dragging and dropping and apply any logic to this.
