ZK 8.6.2 S1
Steps to Reproduce
1. run the code
<grid width="800px" height="200px">
<columns sizable="true">
<column label="1" width="300px"/>
<column label="2" width="300px"/>
<column label="3" width="300px"/>
<column label="4" width="300px"/>
<column label="5" width="300px"/>
<column label="6" width="300px"/>
</columns>
<rows>
<row>
<label value="Item 1.1" />
<label value="Item 1.2" />
<label value="Item 1.3" />
<label value="Item 1.4" />
<label value="Item 1.5" />
<label value="Item 1.6" />
</row>
</rows>
</grid>
2. scroll the grid to the right (grid must be scrolled)
3. shrink the width the 5th column by draging its right border
Current Result
you can drag the right border over its left border.
Amount of extra draggable space = grid scroll position
See the attached video.
Expected Result
the dragging ghost line can't be over than the left border.
Just like you drag the 1st column's right border.
Debugging information
During zul.mesh.HeaderWidget._snapsizing
The snap position calculated with the following block calculates the position based on screen scroll only
if (ofs[0] + dg._zmin >= pointer[0])
pointer[0] = ofs[0] + dg._zmin;
Workaround
for ZK 8.5.1.2
Need to test for side effects
Add grid scroll and document scroll check
<script><![CDATA[ zk.afterLoad('zul.grid', function() { var xColumn = {}; zk.override(zul.grid.Column, xColumn ,{ _snapsizing: function (dg, pointer) { var n = dg.control.$n(), $n = zk(n), ofs = $n.revisedOffset(), innerScrollOffset = $n.scrollOffset()[0], windowScroll = jq(window).scrollLeft(); pointer[0] += $n.offsetWidth(); if (ofs[0] + dg._zmin + innerScrollOffset - windowScroll >= pointer[0]) pointer[0] = ofs[0] + dg._zmin + innerScrollOffset - windowScroll; return pointer; } });//zk.override });//zk.afterLoad ]]></script>
