In some cases it would be great to have minimal width for columns. This is useful when grid has button columns, or size of column should be restricted by header + sort arrow.
My solution for this was extension method:
enableMinWidth: function() {
var $t = this[0];
if (!$t.grid) { return; }
$t.grid.dragMove = function(x) {
if (this.resizing) {
var diff = x.clientX - this.resizing.startX,
h = this.headers[this.resizing.idx],
mW = $t.p.colModel[this.resizing.idx].minWidth || 33,
newWidth = $t.p.direction === "ltr" ? h.width + diff : h.width - diff, hn, nWn, nmWn;
if (newWidth > mW) {
this.curGbox.css({ left: this.resizing.sOL + diff });
if ($t.p.forceFit === true) {
hn = this.headers[this.resizing.idx + $t.p.nv];
nmWn = $t.p.colModel[this.resizing.idx + $t.p.nv].minWidth || 33;
nWn = $t.p.direction === "ltr" ? hn.width - diff : hn.width + diff;
if (nWn > nmWn) {
h.newWidth = newWidth;
hn.newWidth = nWn;
}
} else {
this.newWidth = $t.p.direction === "ltr" ? $t.p.tblwidth + diff : $t.p.tblwidth - diff;
h.newWidth = newWidth;
}
}
}
}
}
var $t = this[0];
if (!$t.grid) { return; }
$t.grid.dragMove = function(x) {
if (this.resizing) {
var diff = x.clientX - this.resizing.startX,
h = this.headers[this.resizing.idx],
mW = $t.p.colModel[this.resizing.idx].minWidth || 33,
newWidth = $t.p.direction === "ltr" ? h.width + diff : h.width - diff, hn, nWn, nmWn;
if (newWidth > mW) {
this.curGbox.css({ left: this.resizing.sOL + diff });
if ($t.p.forceFit === true) {
hn = this.headers[this.resizing.idx + $t.p.nv];
nmWn = $t.p.colModel[this.resizing.idx + $t.p.nv].minWidth || 33;
nWn = $t.p.direction === "ltr" ? hn.width - diff : hn.width + diff;
if (nWn > nmWn) {
h.newWidth = newWidth;
hn.newWidth = nWn;
}
} else {
this.newWidth = $t.p.direction === "ltr" ? $t.p.tblwidth + diff : $t.p.tblwidth - diff;
h.newWidth = newWidth;
}
}
}
}
}
It is not perfect but it works.
It would be great to see something similar integrated in future releases of jqGrid.
