Woot!
Shawn recently added a new method to KiXforms.Net 3.2.16 , so rush over and get your new version now!
The New Method is GetNodeAt()
With this new Method you can do kewl stuff like this:
| Code: |
;region Setup Variables
Break On
$System = CreateObject("Kixforms.System")
If Not $System
$nul = MessageBox("KiXforms.Net Not Initiated. This Script Will Now Close.", "Error", 16)
Quit()
EndIf
$nul = $System.Application.EnableVisualStyles
Global $MovingDelta
$TreeViewNodeArray = Split('Node 0,Node 1,Node 2,Node 3,Node 4', ',')
;endregion
;region Main Form
$Form = $System.Form()
$Form.StartPosition = 1 ;FormStartPosition_CenterScreen
$Form.Size = $System.Size(400, 300) ;(Width,Height)
$Form.Text = "Drag-n-Drop TreeView Node"
$TreeView = $System.TreeView()
$TreeView.Dock = 3 ;Left
$TreeView.MouseDown = "CheckForRightMouseClick($$System.Sender)"
$nul = $Form.Controls.Add($TreeView)
For Each $Node in $TreeViewNodeArray
$TreeViewNode = $TreeView.Nodes.Add($System.TreeNode($Node))
Next
$TreeView.BeginUpdate
$TreeView.SelectedNode = $TreeView.Nodes.Item(0)
$TreeView.Tag = $TreeView.SelectedNode
$TreeView.EndUpdate
$Form.Show ;Displays the Form
While $Form.Visible
$Nul = Execute($Form.DoEvents())
Loop
Exit 0
;endregion
;region TreeView Functions
Function CheckForRightMouseClick($Sender)
$Button = $Sender.MouseDownEventArgs.Button
$CursorXY = $Sender.PointToClient($Sender.MousePosition)
If $Button = $System.MouseButtons_Left
$Node = $Sender.GetNodeAt($CursorXY.x, $CursorXY.y)
If $Node
$TreeView.SelectedNode = $Node
$TreeView.Tag = $Node
$TreeView.BeginUpdate
$TreeViewNode.Tag = $TreeView.SelectedNode
$TreeViewNode = $System.Label()
$TreeViewNode.AutoSize = -1 ;True
$TreeViewNode.BackColor = $TreeView.BackColor
$TreeViewNode.BorderStyle = 1 ;FixedSingle
$TreeViewNode.MouseMove = "ControlMove($$System.sender)"
$TreeViewNode.MouseUp = "ControlMouseUp($$System.sender)"
$TreeViewNode.Text = $TreeView.SelectedNode.Text
$TreeViewNode.TextAlign = 16 ;MiddleLeft
$TreeView.SelectedNode.Remove
$TreeView.EndUpdate
$nul = $Form.Controls.Add($TreeViewNode)
$CursorXY = $Sender.PointToClient($Sender.MousePosition)
$TreeViewNode.Top = $CursorXY.y - ($TreeViewNode.Height /2)
$TreeViewNode.Left = $CursorXY.x - ($TreeViewNode.Width /2)
$TreeViewNode.BringToFront
$MovingDelta = $TreeViewNode.PointToClient($TreeViewNode.MousePosition)
EndIf
EndIf
EndFunction
Function ControlMove($Sender)
If $Sender And ($Sender.MouseButtons & $System.MouseButtons_Left)
$pt1 = $Form.PointToClient($Form.MousePosition)
If ($pt1.x - $MovingDelta.x) >= 0
$Sender.Left = $pt1.x - $MovingDelta.x
EndIf
If ($pt1.y - $MovingDelta.y) >= 0
$Sender.Top = $pt1.y - $MovingDelta.y
EndIf
$Node = $TreeView.GetNodeAt($Sender.Left, $Sender.Top)
$TreeView.SelectedNode = $Node
EndIf
EndFunction
Function ControlMouseUp($Sender)
$Node = $TreeView.Tag
If $Sender.Left > $TreeView.Left And $Sender.Left < $TreeView.Right And $Sender.Top > $TreeView.Top And $Sender.Top < $TreeView.Bottom
$nul = $TreeView.Nodes.Insert($TreeView.SelectedNode.Index, $Node)
EndIf
$Sender.Dispose
EndFunction
;endregion
