database - How to determine value of DbGrid cell during OnMouseMove event -


I have an on-house main event, during which I want to get the value of some cells (not underneath the mouse) . In fact, the question is how can the cell be used, using the X and Y coordinates without the selection, changing the focus etc?

Toffig, you can use the MouseCoord process to get the current row and call To show the value of the status [Col., line] , you must set the value to the value of the property and create a new class descendant to use the protected property.

Check this code 

  type THackGrid = class (TCustomDBGrid); // Create a new class to access the protected property process TForm1.DBGrid1MouseMove (Sender: Tubect; ​​shift: TIFFTTSTATE; x, y: integer); Var Cell: Tigrid Coord; Line, col: integer; OrigActiveRecord: integer; inherited from; Cell: = DBGrid1.MouseCoord (X, Y); Colonel: = Cell. X; Line: = cell why; If DGITITALS in DBibrite 1 Option then dec (line); // If the headings are shown adjust the Row Index (-1); If DGIdactor in DB Grid 1 The alternative is then December (Colonel); // If the pointer is shown, adjust the column index (-1); If Thakgid (DBGrid1) .DataLink Active and starts (Row> = 0) and (Colonel> = 0), then the Oriental Record starts: = Hagrid (DBEGEED1) .DataLink.ActiveRecord; // Try to save the original index THACKGrid (DBGrid1) .DataLink.ActiveRecord: = Row; Label1.Caption: = DBGrid1.Columns [Col.] .Field.AsString; // Show the current value in Half Grid (DBigrid 1) at the end of a televac DataLink Activivorld: = Objective record; // index ending the end; End; End;

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
