Button at the same height of the selected subnode of treeview

[SergioFeitoza]

Please help me with the following. In my code I have a Tunitreeview as in the figure attached

I need that the blue button that you see in the right side of the selected node / subnode is positioned  at the same “top” dimension of the selected subnode

In VCL this can be done using TreeView.SelectedNode.Bounds.Y (for Y position) as in this post https://stackoverflow.com/questions/13068419/grab-the-location-of-selected-node-of-treeview

My problem is that I could not find  a Unigui property corresponding to  “Bounds.X” or  “Bounds.Y”

Could suggest me a way of doing this ?

Will you consider scrolling?!

Hi Sherzod. The idea is interesting but  I do not know how could I implement. Is there something like this in the demos ?

The reason for the need of putting  the button - to call the attention for the clicked subnode - is that i I will include a text in the button (like a Hint)

Is there something like  the "bounds.X" in Unigui ?

P.S:  Is there any demo with something like draging a  component from a position to other, using the mouse ? or how to write the coordinates of the position of a point in the screen?

Hi,

For example, without considering scrolling:

UniTreeView.ClientEvents.ExtEvents -> 

function select(sender, record, index, eOpts)
{
    var grid=this.ownerGrid;
    var gridY=grid.getY();
    var elem=grid.getEl().select('table[data-recordindex="'+ record.id +'"]').elements[0];
    if (elem) {
        MainForm.UniButton3.setPosition(
          150,
          Ext.get(elem).getY()-gridY+5
        )
    }
}
