SimpleGrid

[Grincheux]

I have installed SimpleGrind into my Cfe Program.
I would like to know if it is possible to avoid the user enters non numeric characters.
He is allowed to enter negative and positive numbers only.


On the image, I have a matrix 3x3
Do I have to create a dummy column for having the same width for all colums?


That's all for now.

I have added a dummy column.
Is it possible to align the first column?
Is it possible to align the grid header?

Hello Grincheux,

As it is currently; it is not possible to override the alignment of the row and column headers (GSA_GENERAL).
However you can hide the row and column headers if you don't need them.

Code Select Expand

//Hide row headers
SimpleGrid_SetRowHeaderWidth(hgrid,0);
//Hide column header
SimpleGrid_SetHeaderRowHeight(hgrid, 0);

The cells in the columns can be aligned using the following:

Code Select Expand

VOID SimpleGrid_SetItemTextAlignmentEx(
     HWND hGrid
     INT iCol
     INT iRow
     DWORD dwAlign
     );
/*Parameters
hGrid
     Handle to the SimpleGrid control.
iCol
     The column index of the item.
iRow
     The row index of the item.
dwAlign
     One of the following alignments: GSA_LEFT, GSA_GENERAL, or GSA_RIGHT.

Return Values
The return value is not meaningful.
*/

You can use the SGN_KEYDOWN notification monitor the key presses in a cell and respond to them appropriately.

Setting column width:

Code Select Expand

INT SimpleGrid_SetColWidth(
     HWND hGrid
     INT iCol
     INT nWidth
     );
/*Parameters
hGrid
     Handle to the SimpleGrid control.
iCol
     The index of the column.
nWidth
     The desired width (in pixels) of the column.
     
Return Values
ERROR_SUCCESS otherwise SG_ERROR if desired column is out of bounds.

Windows does not allow to align the first column.
If you want to do this, recreate the first column and remove the first column;

Hello Grincheux,

The grid columns and rows are numbered beginning with 0.  So the first column is column 0 and first row is row 0.

Code Select Expand

SimpleGrid_SetItemTextAlignmentEx(hgrid, 0,0,GSA_RIGHT);
should set the contents of the first cell to a right alignment.

Code Select Expand

SimpleGrid_SetColWidth(hgrid,0,100);
should set the width of the first column to 100 pixels.
