Setting a Row or Column of a GridBadLayout to a Particular Size
By default, the width of a column in a gridbag layout is set to
the widest component in the component. This example demonstrates how
to increase the width of the column to a particular size. The same applies to
rows of a gridbag layout.
See Creating a GridBagLayout for an example on how to
use a gridbag layout.
// Sets the minimum width for column c to be w pixels wide
public void setColumnMinWidth(GridBagLayout gbl, int c, int w) {
int[] ws = gbl.columnWidths;
if (ws == null) {
ws = new int[c+1];
} else if (ws.length < c+1) {
ws = new int[c+1];
System.arraycopy(gbl.columnWidths, 0, ws, 0, gbl.columnWidths.length);
}
ws[c] = w;
gbl.columnWidths = ws;
}
// Sets the minimum height for row r to be h pixels high
public void setRowMinHeight(GridBagLayout gbl, int r, int h) {
int[] hs = gbl.rowHeights;
if (hs == null) {
hs = new int[r+1];
} else if (hs.length < r+1) {
hs = new int[r+1];
System.arraycopy(gbl.rowHeights, 0, hs, 0, gbl.rowHeights.length);
}
hs[r] = h;
gbl.rowHeights = hs;
}
