I haven't studied the code of TcxTreeList as a whole, but I imagine that the image Property ControlContainer: TcxContainer read GetControlContainer īut I have no idea whether you could invoke any of these interfaces from a separate Delphi app, even if they are of any use for what you're at. Property Control: TWinControl read GetControl It has message handlers as follows (in addition to TCustomEdit's) ']įunction GetControlContainer: TcxContainer TcxCustomInnerTextEdit is declared in the Devex VCL source in the unit cxTextEdit.Pas and is a descendant While you edit one of the data nodes in the tree, a window of class TcxCustomInnerTextEdit is created.

Reading the documentation from Devexpress I can see the following class hierarchy: TcxTreeList -> TcxCustomTreeList -> Tc圎xtEditingControl -> Tc圎ditingControl -> TcxControl -> TCustomControl, but unfortunately I don't know what kind of windows messages to send in order to get data.įor example: in order to get data for a standard Tree View I send messages with parameters like TVGN_CHILD, TVGN_NEXT, TVM_GETITEM and so on in the right sequence.Ĭan someone suggest me how to get data for the TcxTreeList control? Tree Views, List boxes, Memos, List Views and so on) sending the right windows messages, but I don't know how to do that for this kind of custom controls. I know how to get data from standard controls in external applicatioins (i.e. I need to get all data from a TcxTreeList (a custom Devexpress control) from an external application.
