LondonNDIB Posted December 15, 2005 Posted December 15, 2005 Gui still confuses me With treeview... say I have something like this: + Category 1 |_ Item 1 |_ Item 2 |_ Item 3 I know when the user presses the + it folds/expands the Category 1. Is there some way that the + can be a control with its own event? Basically, I have hundreds of "Category"s each with some unknown number of "Item"s and it takes too long to generate the entire treeview with them all. What I want to achieve is that WHEN the user presses +, it runs a function that determines what should be in there. At first glance, this doesn't seem possible because the + doesn't even exist unless the "Category" has at least one "item" in it. I suppose I can get around that with a dummy item that gets deleted after the + is pressed... hmm. But I don't even know how I would go about calling the function with the + press. Any ideas? Thanks!

tonedeaf Posted December 15, 2005 Posted December 15, 2005 This is an interesting problem. I would also like to see how it can be done.
ReFran Posted December 15, 2005 Posted December 15, 2005 (edited) Here an example from ..... (Valuater if I remember right) Execute it and it will show you every item you have clicked (also Parents). HTH, Reinhard #include <GUIConstants.au3> Dim $curlevel = 1 Dim $aTree = StringSplit(FileRead("Tree.dat", FileGetSize("Tree.dat")), @LF) GUICreate("title") $hTree = GUICtrlCreateTreeView(5, 5, 300, 200) Dim $ahDepth[100] $ahDepth[0] = $hTree For $i = 1 to $aTree[0] $line = StringStripCR($aTree[$i]) $markpos = StringInStr($line, "#") If $markpos <> $curlevel Then $curlevel = $markpos $ahDepth[$markpos] = GUICtrlCreateTreeViewItem(StringMid($line, $markpos+1), $ahDepth[$markpos-1]) Next GUISetState() While 1 $nMsg = GUIGetMsg() if $nMsg > $ahDepth[$markpos] - Ubound($aTree) + 1 then msgBox(0,"",$aTree[$nMsg-($ahDepth[$markpos] - Ubound($aTree)+1)]) EndIf If $nMsg = -3 Then Exit Wend Here the Tree.dat file for the TV example, which must be in the script dir. #Level 1.1 #Level 2.1 #Level 2.2 #Level 2.3 #Level 3.1 #Level 4.1 #Level 3.2 #Level 2.4 #Level 3.3 #Level 1.2 #Level 2.5 #Level 2.6 Edited December 15, 2005 by ReFran
