Detect Column Resize In DataGrid

[dickey]

Hello all,

I have coded my own filters for the DataGrid object.

I have a field that performs a type ahead search across all the columns of the DataGrid (background/irrelevant), and a collection of fields sitting above the header fields of the grid which perform a cumulative type ahead search upon the column to which they relate (relevant).

I was wondering,

+ in the first instance whether each field could inherit the width property from the corresponding column in the DataGrid, and if that were not possible;

+ in the second instance whether upon column resize in the DataGrid a message fires which I could customise to resize my filter fields to maintain a coherent width/alignment. I couldn't spot what I needed in the API, but I imagined a handler something like: on ResizeDataGridColumn pColumn -- I could then grab the column width and column margins for pColumn and apply them to my filter fields (or use get the dgFormattedWidth of group "xyz").

Using a similar technique I could then maintain the width/alignment of my column totals at the base of the DataGrid.

Any assistance greatly appreciated. Kind regards, Andrew

zryip theSlug was so kind as to email me the following solution via the LiveCode Developer List:

Hi Andrew,

You can use the dgColumnWidth property of the datagrid on the datagrid
group script to get the size of a column being resized..

setprop dgColumnWidth [pColumn] pValue
put pColumn & "Filter" into tColumnFilterField
put pColumn & "Sum" into tColumnSumField
changeRectOfField tColumnFilterField, pValue
changeRectOfField tColumnSumField, pValue

pass dgColumnWidth
end dgColumnWidth

Where:
- pColumn is the column name
- pValue is the column width

My thanks to zryip for his response.

Kind regards, Andrew
