GridCtrl column width simple question [message #21056]

Hello all

I have done a simple function to write data to a GridCtrl:

void Grid_Write(int row, int col, char *str)

When the row or the column does not exist, it does:

	if (row > grid.GetRowCount()-1) {
		for (int i = grid.GetRowCount(); i < row+1; ++i)
			grid.AddRow("", 100);	
	}

Doing that with more than one column I get this: the first columns get so thin that are almost hidden.

index.php?t=getfile&id=1702&private=0

Do you know how to get all columns with same width if they - as in this case - are not added to the grid at the same time and data is included in between?

Best regards
Koldo

Please turn off column repainting when adding columns:

void Grid_Write(int row, int col, char *str)
{
        grid.Ready(false);
	if (row > grid.GetRowCount()-1) {
		for (int i = grid.GetRowCount(); i < row+1; ++i)
			grid.AddRow("", 100);	
	}
        grid.Ready(true);
}

This must be done only in Proportional mode and only if you're adding columns when grid is visible.

Hello unodgs

Almost ok. Now I initialize the grid with:

grid.ResizeColMode(0);

that is Absolute mode, and it works:

	grid.Ready(false);
	if (col > grid.GetColumnCount()-1) {
		for (int i = grid.GetColumnCount(); i < col+1; ++i) 
			grid.AddColumn("", 100);
	}		
	tabGrid->grid.Ready(true);
