Adding data from outside the grid about pluto_grid HOT 11 CLOSED

Fantastic, thank you so much! I think you're on to a real desktop/web grid for businesses everywhere!

from pluto_grid.

You can create a row that matches the current column information with getNewRow and getNewRows of stateManager.

Change the cell value of the created row to the desired value.

After the change, create a row to be added with insertRows, prependRows, appendRows, etc. of the stateManager.

Please let me know if you need more explanation or examples.

Is it the case of using by providing List to StreamBuilder?

            child: StreamBuilder<List<PlutoRow>>(
              stream: ...,
              builder: (context, snapshot) {
                return PlutoGrid(
                  columns: columns,
                  rows: snapshot.data,
                  onChanged: (PlutoOnChangedEvent event) {
                    message(context, event.toString());
                  },
                  onLoaded: (PlutoOnLoadedEvent event) {
                    stateManager = event.stateManager;
                  },
                );
              }
            ),

It doesn't work, currently passing stream data to the rows property.

Passing stream data to the row property to work would be added in the future.

Not now, but by adding a constructor like PlutoGrid.streamBuilder for example.

Below is an example of general row addition and deletion.

example

...

return PlutoGrid(
  columns: columns,
  rows: rows,
  /// Handle when the cell value changes.
  /// class PlutoOnChangedEvent {
  ///   final int columnIdx;
  ///   final PlutoColumn column;
  ///   final int rowIdx;
  ///   final PlutoRow row;
  ///   final dynamic value;
  ///   final dynamic oldValue;
  /// ...
  onChanged: (PlutoOnChangedEvent event) {
    message(context, event.toString());
  },
  onLoaded: (PlutoOnLoadedEvent event) {
    stateManager = event.stateManager;
  },
);

...

/// Adding row.
stateManager.appendRows([
  PlutoRow(cells: {
    'text': PlutoCell(value: ''),
    'number': PlutoCell(value: 0),
  }),
]);

...

/// Removing current row.
stateManager.removeCurrentRow();

It was exactly as you described, but I didn't realize the stateManger was the route to do this. Thank you!!!

It is not documented yet. It is not enough to develop it alone. I will work hard.

I just ran into your pluto grid the other day. I am a new flutter dev, but have been doing pascal for decades. Your grid is what a business grid should be. I probably can not help code, but I will gladly test, or help with documentation if you like. Great job so far!!!

from pluto_grid.

Yes, anything is good.

I've just created a grid, but I haven't used it except for testing.

That's why problems, methods, documentation, and tests that occur during use are all good.

The Pluto series aims to develop a package for Admin or Cms.

There is also one called PlutoMenuBar.

I plan to keep making these things.

I will go over it this weekend, and see what I can do to help. I see that you have implemented stateManager.appendRows(), if you added a removeRows(), the stream updates would be simple.

You have really done so much with key handling and everything. Bravo!

from pluto_grid.

Thanks, I will finish adding the test code now, and I will work on adding removeRows().

@bosskmk Hi there, just tried this feature of adding new rows, but there is a problem.

I am implementing a feature of copying and pasting rows, and what happens is that the newly added rows have same cell key as the ones copied and any change, even the click of mouse is depicted on the rows that were originally copied.

I have thought of a work around, that is the I get the data from the rows that are copied and create new PlutoRow for the data. Would you also recommend this workaround or is there something better?

from pluto_grid.

1. Created a method that takes values from a row and creates a desired object(List) using statemanager.currentSelectingRows
2. Mapped the list of object to PlutoRow
3. Then appended the plutoGrid using statemanager.appendRows
