[Implemented] Manipulate ExplorerListGadget Column

fsw · Post by **fsw** » Thu Jun 12, 2003 1:12 am

Would be nice to be able to change the width of the name column by command like SetExplorerColumnWidth(GadgetID,ColumnID,Width).
GetExplorerColumnWidth(GadgetID,ColumnID,Width) would also be nice (so it can be stored and while the application starts read the value and set it.

Also to be able to delete a column would be nice (the TYPE column is mostly not needed).
Maybe just set the column width to 0

The ColumnWidth function could be useful for the other ListGadgets too...

(Implemented trough the gadget attribute: '#PB_Explorer_ColumnWidth')

And on that note, to be able to add columns would be great. (ie. attributes of the files) Also it would be great to get the right click message when you right-clicked on the header.
Just some thoughts. Great gadget!

Thanks

Hi fsw and RJP Computing,

To add a column, just use AddGadgetColumn() command. I try it with explorergeadget and it works well.

I'm wrinting a lib for listicongadget and i have tested the command to set width of column on ExplorerGadget. It works well.
ExplorerGadget is a listiconGadget.

Use this message to set column width :

sendmessage_(GadgetID(#ExplorerGadget),#LVM_SETCOLUMNWIDTH , ColumnIndex,Width)

Use this message to get column width :

sendmessage_(GadgetID(#ExplorerGadget),#LVM_GETCOLUMNWIDTH , ColumnIndex, 0)

Yes, ExplorerListGadget is a Listicon, and you can easily modify it
with the API commands.

However, I don't know, what happens, if you remove a column atm, as the
Gadget will continue to write data to it, so better set the with of the unused
columns to 0.

btw: ExplorerTreeGadget is a usual TreeGadget, I'm sure you can find
some hacks there as well

Hello, I wonder how we then can fill that column. Perhaps with some callback (that I still can't understand at all)?
For example I'd like to show there the fist 100 byes of each file, if the file is a .txt
Is it possible? I could scan all the files after every refresh, but how can I know that when a refresh has finished?
