### Plugin Implementation Base (PandasTable)

Source: https://pandastable.readthedocs.io/en/latest/examples

Shows the fundamental structure for implementing a custom plugin for PandasTable. It involves subclassing the `Plugin` class and ensuring a `main()` method is present, which is called by the application to launch the plugin. The example includes getting the current table and adding a plugin frame.

```Python
from pandastable.plugin import Plugin

# ... inside a plugin class that inherits from Plugin ...

def main(self):
    self.table = self.parent.getCurrentTable() #get the current table
    #add the plugin frame to the table parent
    self.mainwin = Frame(self.table.parentframe)
    #pluginrow is 6 to make the frame appear below other widgets
    self.mainwin.grid(row=pluginrow,column=0,columnspan=2,sticky='news')
```

--------------------------------

### Setup Query Input and Filter Buttons in PandasTable

Source: https://pandastable.readthedocs.io/en/latest/_modules/pandastable/dialogs

The `setup` method configures the user interface for the `QueryDialog`. It creates a label for entering the query, an Entry widget bound to a `StringVar` for input, and buttons for applying the filter and adding manual filters. It also includes frames to organize these widgets.

```Python
def setup(self):

        qf = self
        sfont = "Helvetica 10 bold"
        Label(qf, text='Enter String Query:', font=sfont).pack(side=TOP,fill=X)
        self.queryvar = StringVar()
        e = Entry(qf, textvariable=self.queryvar, font="Courier 12 bold")
        e.bind('<Return>', self.query)
        e.pack(fill=BOTH,side=TOP,expand=1,padx=2,pady=2)
        self.fbar = Frame(qf)
        self.fbar.pack(side=TOP,fill=BOTH,expand=1,padx=2,pady=2)
        f = Frame(qf)
        f.pack(side=TOP, fill=BOTH, padx=2, pady=2)
        addButton(f, 'find', self.query, images.filtering(), 'apply filters', side=LEFT)
        addButton(f, 'add manual filter', self.addFilter, images.add(),
                  'add manual filter', side=LEFT)
```

```Python
    def getRowPosition(self, y):
        """Set row position"""

        h = self.rowheight
        y_start = self.y_start
        row = (int(y)-y_start)/h
        if row < 0:
            return 0

```Python
def getRowsFromMask(self, mask):
        df = self.model.df
        if mask is not None:
            idx = df.ix[mask].index
        return self.getRowsFromIndex(idx)
```

```Python
class QueryDialog(Frame):
    """Use string query to filter. Will not work with spaces in column
        names, so these would need to be converted first."""

    def __init__(self, table):
        parent = table.parentframe
        Frame.__init__(self, parent)
        self.parent = parent
