How to detect tlistview cell that was clicked
I want to change the value in a tlistview cell (subitem) when the user clicks it. I can get the x,y coords in mousedown, but isn't there a function to translate that? Can't find it. Jeremy

If you have the X, Y coordinate you can call
function TListView.GetItemAt(X, Y: Integer): TListItem;
It will return the TListItem clicked or nil.

Thanks, I missed that. But, it doesn't give me the subitem.

You can iterate the Columns property of the ListView to find the cell. By
example:
procedure TForm1.ListView1MouseDown(Sender: TObject; Button: TMouseButton;
Shift: TShiftState; X, Y: Integer);
var
Item: TListItem;
I, W: Integer;
Col: Integer;
begin
Item:= ListView1.GetItemAt(0, Y);
if Assigned(Item) then
begin
I:= 0;
W:= 0;
Col:= -1;
while (I< ListView1.Columns.Count) and (Col< 0) do
begin
Inc(W, ListView1.Columns[I].Width);
if X< W then
Col:= I;
Inc(I);
end;
if Col>= 0 then
Label1.Caption:= 'Item: ' + Item.Caption + ' Column: ' +
IntToStr(Col)
else
Label1.Caption:= EmptyStr;
end;
end;

Another (more simple) example:
procedure TForm2.ListView1MouseDown(Sender: TObject; Button: TMouseButton;
Shift: TShiftState; X, Y: Integer);
var
Item: TListItem;
W: Integer;
Col: Integer;
Text: String;
begin
Item:= ListView1.GetItemAt(0, Y);
if Assigned(Item) then
begin
W:= 0;
Col:= -1;
repeat
Inc(Col);
Inc(W, ListView1.Columns[Col].Width);
until X< W;
// Do with 'Col' what you want
Text:= 'Item: ' + Item.Caption + ' - Column: ' + IntToStr(Col);
if (Col> 0) and (Col<= Item.SubItems.Count) then
Text:= Text + ' - Subitem: ' + Item.SubItems[Col-1];
Label1.Caption:= Text;
end;
end;

The information is available when using LVM_SUBITEMHITTEST.
http://msdn.microsoft.com/en-us/library/bb761229(VS.85).aspx
For example:
uses
ComCtrls, CommCtrl;
type
THitInfo = record
HitTests: THitTests;
HitItem: Integer;
HitColumn: Integer;
end;
function ListView_SubItemHitTest(hwndLV: HWND; var pinfo:
TLVHitTestInfo): Integer;
begin
Result := SendMessage(hwndLV, LVM_SUBITEMHITTEST, 0, Longint(@pinfo));
end;
function GetSubItemHitTestInfoAt(Handle: THandle; X, Y: Integer):
THitInfo;
var
Info: TLVHitTestInfo;
begin
Info.pt := Point(X, Y);
ListView_SubItemHitTest(Handle, Info);
Result.HitColumn := Info.iSubItem;
Result.HitItem := Info.iItem;
Result.HitTests := [];
if ((Info.flags and LVHT_ABOVE) <> 0) and (Y < 0) then
Include(Result.HitTests, htAbove);
if (Info.flags and LVHT_BELOW) <> 0 then
Include(Result.HitTests, htBelow);
if (Info.flags and LVHT_NOWHERE) <> 0 then
Include(Result.HitTests, htNowhere);
if (Info.flags and LVHT_ONITEM) = LVHT_ONITEM then
Include(Result.HitTests, htOnItem)
else
begin
if (Info.flags and LVHT_ONITEMICON) <> 0 then
Include(Result.HitTests, htOnIcon);
if (Info.flags and LVHT_ONITEMLABEL) <> 0 then
Include(Result.HitTests, htOnLabel);
if (Info.flags and LVHT_ONITEMSTATEICON) <> 0 then
Include(Result.HitTests, htOnStateIcon);
end;
if (Info.flags and LVHT_TOLEFT) <> 0 then
Include(Result.HitTests, htToLeft);
if (Info.flags and LVHT_TORIGHT) <> 0 then
Include(Result.HitTests, htToRight);
end;
Which can be used in the following way:
procedure TForm1.ListView1MouseDown(Sender: TObject;
Button: TMouseButton; Shift: TShiftState; X, Y: Integer);
var
HitInfo: THitInfo;
LV: TListView;
begin
LV := (Sender as TListView);
HitInfo := GetSubItemHitTestInfoAt(LV.Handle, X, Y);
// use HitInfo
end;

Gentlemen, thank you. This is a great reminder that windows messaging is
really useful, despite being a little daunting in the beginning. Also, I
was not aware of TControl.Perform, which sure makes this stuff much easier.

Is there any advantage for placing TEdit on every subItem clicked?

To use or not to use Delphi
Sadly, it seems to me that there is a sort of race between the two threads, for and against using Delphi in new projects, with more or less the same users posting in both threads. Arguments are fiercely debated in both camps. Borland had their own vision. As a community, now that Delphi has changed ownership I believe we should try to be more consistent, more clear, and more articulate in what we expect from Embercadero in terms of Delphi. We can contribute to keeping Delphi alive and moving in the right direction.

Making a cell editable on clicking the cell
Hi, I am trying to make a cell editable as soon as the user clicks on that particular cell in the .net data grid.

Instead I would like to make this possible without even clicking on the Edit button. There will be only one button (Save) to save the changes done on the grid. Is there any way to do it ?

To use or not to use Delphi
Sadly, it seems to me that there is a sort of race between the two threads, for and against using Delphi in new projects, with more or less the same users posting in both threads. Arguments are fiercely debated in both camps. Borland had their own vision. As a community, now that Delphi has changed ownership I believe we should try to be more consistent, more clear, and more articulate in what we expect from Embercadero in terms of Delphi. We can contribute to keeping Delphi alive and moving in the right direction.

Spreadsheet component for use in Delphi VCL 2010
Good day I have been using the Flexcel component for reading and writing Excel spreadsheets in my Delphi VCL projects for some while and have been very happy. Unfortunately, though, a version for use with Excel 2007 format files (.XLSX) has been promised for years now but just never arrives and I have reached a stage where I just have to update some of my software. Can any body suggest alternatives and comment on their experience with these? I have no objection to buying a component although all my programs are for academic use by myself and colleagues/friends so cheaper would...

Click...click...click
I was listening today to a photography podcast at: www.photography.ca/blog and the host Marko described the loss of the hard drive which contained a backup of all his images. He said that one morning he tried to boot up, and the drive just went "click... click... click" but never did anything more, and of course wouldn't boot. Is there a reasonable chance that Spinrite could fix that, or does that behavior indicate a physical problem with the drive head or electronics?

Delphi XE8 Send Notification from Parse using VCL app

Delphi 6
In preparation for applying a bug fix to one of the VCL modules (AxCtrls.pas), I have been trying to compile the original source code for the module in order to reproduce exactly the existing dcu. I have copied AxCtrls.pas to an empty directory, and have found that doing: dcc32 -q AxCtrls -$D- -$L- gives me a dcu which is identical in size to the one on Delphi6/Lib, with identical contents except for a few bytes near the beginning, which I assume are a compliation timestamp. However, I have been unsuccessful in duplicating the debug dcu in Delphi6/Lib/Debug. Using "-$D+ -$L+&q...
How to detect if code executes in a VCL application and needs to use Synchronize?
Hello newsgroup, this is my current logic in a thread to check if the 'HandleIncomingData' call needs to be synchronized: if System.IsConsole then begin HandleIncomingData; end else begin Synchronize(HandleIncomingData); end; It works fine, but only if the console application does not open VCL Forms. For example, I have a GUITestRunner unit test project which also uses APPTYPE CONSOLE to open a console window for debug output. In this case, System.IsConsole is True, but the Synchronize is necessary to avoid applica...
Making a cell editable on clicking the cell
Hi, I am trying to make a cell editable as soon as the user clicks on that particular cell in the .net data grid. Usually, the way we do is, we click the edit button and the cells become editable and two buttons(Update and Cancel) appear. Instead I would like to make this possible without even clicking on the Edit button. There will be only one button (Save) to save the changes done on the grid. Is there any way to do it ? I hope I am clear. Thanks in advance. Prasad P Take a look at the following article, which shows how you can hightlight the row by clicking anywhere in the ro...
Using Delphi 7 and Delphi 2010
I had a project in Delphi 7. I worked on it in Delphi 2010. When I try to open the .dpr again in Delphi 7, the IDE toolbar widens across both monitors, and Delphi 7 locks up. It appears that Delphi 2010 modifies the .dpr in a way that makes Delphi 7 unable to open it again. All my forms & units appear to open fine in D7 after D2010, except for the warnings on the ExplicitHeight and ExplicitWidth properties being missing... I can easily recreate the .dpr, but is this expected behavior? Thanks. Tom Field wrote: > I had a project in Delphi 7. > > I worked o...

Is there a way to detect selected value when a mouse is held-down over a context menu( opened by right click on textbox) using javascript?
Is there a way to detect selected value when a mouse is held-down over a context menu( opened by right click on textbox) using javascript? Means find out which value (Copy,cut,paste, delete, select all) is selected by mouse click from context menu using javascript. No you can not tell what was selected from the context menu. (You can write your own.) One example is: http://www.dynamicdrive.com/dynamicindex1/contextmenu.htm but you would have to build the functionality of the orginal menu with code.
