On my OnExit event of Edit1I have the following code: Delphi Caret Position Tedit 10; Edit2 has the focus. However, there is no caret in it.I can start typing but it's confusing as. For the caret build into standard edit controls (TEdit, TMemo in Delphi) or created by a call to the CreateCaret API function the Windows API has a function GetCaretPos, but the problem (for you) is that this function only returns the (last) position of a caret inside the application that calls it. You cannot get the position of the caret.
The cause of this behavior is that the TextBox created by a cell editor sets its caret to the position where the mouse was clicked on raising the MouseDown event. If TableView.EditorShowMode is MouseUp, the TextBox is created after the MouseDown event is raised, so it cannot set its caret position. This is expected behavior. Note: Controls that display text use either the Caption property or the Text property to specify the text value. Which property is used depends on the type of control. In general, Caption is used for text that appears as a window title or label, while Text is used for text that appears as the content of a control.
Delphi Tedit Set Caret Position
Greetings collective wonderfolk of the internet.I'm trying to underline specific words in a TEdit (actually a TNxEdit from Berg NextSuite - but it's a derivative of TEdit). However in order to do this I need to know the pixel coordinates of said word.This is fairly easy to do if the start of the text is visible, however I can't work out how to do it if the start of the text has been scrolled off the end.Is there some way of determining the exact coordinates of a given word directly?

Failing that, determining which text is visible in the edit and which isn't? Or some other ingenious method.Edit1: To cover some of the current answers:The requirements are to implement a spell checker on a column of a TNxGrid component, which limits me to TNxEdit. If I could choose which component I used I would have switched by now:(I can do the drawing the line. TNxEdit has a canvas that allows me to draw the underline quite happily providing I can work out the correct coordinates.If the start of the edit text is visible, i.e.
There's no scrolling off the front, then I can determine the correct start position and the length of the line using TextExtent.The issue comes in the scenario where the start of the text has scrolled off the front. Not being able to determine how much is scrolled off the front means I can't work out the starting position for the line. The length of the line becomes a problem if the word I want to highlight is also partially scrolled. TEdit is a Delphi wrapper for system Win32 Edit class and it doesn't provide any functions to set underline attribute on a specific word, neither TEdit add such a feature.

I suggest you consider using a more powerful class, component in delphi, as TRichEditSaid that, if you like to face complex task, try calculating string extent given a font (see GetTextExtentExPoint and similar) to get the x start/end position of the line, (also consider the border of Edit to add some x offset) and draw a line on the HDC (TCanvas).
I got two TEdit controls. When I tab out of edit1,edit2 receives the focus. On my OnExit event of Edit1I have the following code: procedure TForm1.Edit1Exit(Sender: TObject);beginedit2.Enabled:= false;edit2.Enabled:= true;edit2.setfocus;end;Edit2 has the focus. However, there is no caret in it.I can start typing but it's confusing as I do not knowwhich control has the focus.I'm more interested on what's with the flipping of theEnabled property that's causing some messages to be notfiring properly? For instance edit2's OnEnter eventis not being triggered.This is on D2006 if it matters at all.Thanks for the reply.
Found an issue when OnActive for MainForm activates another form. TMainForm.OnActivate;beginChildForm.ShowModal;end;Control focus is set but does not work. The work around I found was sending PostMessage(Handle, WMSETFOCUS, 0, 0); to the form handle. Procedure TChildForm.FocusControl(AWinControl: TWinControl);begintry// WMSETFOCUS, 0, 0);PostMessage(AWinControl.Handle, WMSETFOCUS, 0, 0);if AWinControl.CanFocus thenAWinControl.SetFocus;excepton E: Exception dobeginError(Self, E);end;end;end.
