Hi,
i use next code:
void OpenReport(AnsiString MyString )
{
if(MyString == "MYITEM")
{
ShowMessage(" item found" );
}
}
void __fastcall TfrmReports::TreeView1Click(TObject *Sender)
{
TTreeNode *ATreeNode;
ATreeNode= TreeView1->Selected;
if (ATreeNode->Parent != 0 )
{
if (ATreeNode->Parent->Text == "Algemeen")
{
OpenReport(ATreeNode->Text, );
}
}
}
i have the next treeview
Algemeen
Mystring
Otherstring
Justonother string
hello
Mystring1
Mystring2
Mystring3
etc.etc.
the code work ok,
if i press Algemeen->MyString the messagebox is shown.
if i press onother string there is no messagebox.
but after i pressed Algemeen->MyString i click on the plus sign (+) from
another node,
this time the messagebox is shown to.
how can i solve this?

This code won't work the way you describe. It doesn't even
compile.
This line:
This line
a message to display. Only a node with the text
"MYITEM" will display the message.
clicked the tree and the responsive node is still selected so
it responds.
the message to display when you first select a responsive node.
The message won't display each time you click the node, if it's
already selected.
If you want that then you can leave your code in the OnClick event
and set a bool in the OnCollapsing and OnExpanding events to
inhibit display of the message.
The problem with this solution is that clicking anywhere in the
tree except on node text or a + or - sign causes the message to
display.
A better solution is to use the DisplayRect property of the responsive
nodes in conjunction with the MouseDown, MouseUp or MouseMove
events of the tree to determine whether you have hit, or are about to
hit, a responsive node.

displaying a messagebox on every single click regardless of where that click
actually occurs, and then you are testing the current selected item, which
has not changed.
If you only want to display the message when the user clicks on an actual
item, you need to use the TreeView's GetHitTestInfoAt() method during the
click to retreive information about the location where the click is actually
occuring, and then act accordingly.

Hi
I want to perform some action when I click on an item
on the treeview list, but only when the click was on a item
and not on "+/-" plus or minus signs
What method should i use?
Thanks Sorin
 

Sorin,
Use the OnMouseUp/OnMouseDown events on the TTreeView. In this event you are
passed a couple of parameters (X&Y) which you can put into a
TreeView.GetHitTestInfoAt(X,y) query.
If you get back a htOnLabel I think you may get what you are looking for
(take a peek at the online help for GetHitTestInfoAt.

Use the OnChange event of the TreeView as the Node you have clicked on is
passed to that event which you can setup like so:
procedure TForm1.TreeView1Change(Sender: TObject; Node: TTreeNode);
begin
if Node.Text = 'Text' then
begin
end;
{
or if each node has it's own image index do the following
}
case Node.ImageIndex of
0: ;
1: ;
2: ;
3: ;
4: ;
end;
end;
the event is only fired when changing a node (even when using a keyboard),
so you don't have to worry about checking the cursor position, etc.
 

Hi,
I set the MultiSelect Property of the TreeView to true and also set the
msControlSelect and msShiftSelect to true.
when I want to change the focused node programmatically, if the focused node
is one of the selected nodes, focus process not worked. And OnChange and
OnChanging methods do not call.
I used both these commands separately and together:
Tree->Selected = Tree->Items->Item[i];
Tree->Items->Item[i]->Focused = true;
What is my wrong? Any help would be appreciated.
Thank you,
Mehrdad
 

If an item is already selected, reselecting or refocusig it will not trigger
OnChange again.
That is normal because nothing changes at all. Thus you should manually
handle it.
for example:
if ( Tree->Selected != Tree->Items->Item[i] )
Tree->Selected = Tree->Items->Item[i]; // if the selection
changes, then just change it
else
call OnChange function manually here ( e.g OnTree1Change ( this,
... ); // else just call on change manully

Thank you for your answer. I did it, but still the new selected term not
focused.

himm, I think I understand you wrong.
I didn't encounter a problem like that yet.
But what about deselecting first by assigning NULL, then selecting it again.
it may work.

Hi,
I have a TTreeView with static nodes and sub-nodes, and I am trying to find
a way to know which node/ sub-node exactly selected under TreeView OnChange
event. Taking in consideration that some of the sub-nodes have the same
text.
So can someone help me please and tell me how I can do so?
Thanks in advance for your time and efforts.
Best Regards
