Empirica TradePad application is a multi-window desktop application, which supports:

Tables

Most TradePad tables has few common functionalities described in details in the following paragraphs.

Columns - resizing and reordering

Order of columns can be changed in every TradePad table. You can also change columns’ width. Every resize or reorder of columns is saved at application shutdown and will be restored with the next TradePad launch.

Columns - visibility

Columns visibility can be set using the Column visibility Icon button in the upper right corner of every table. Clicking it opens a list of all columns where columns visibility in the table can be set to in or off. The way the columns are displayed in the table can be controlled by setting Horizontal Scroll and using Pack All/Selected Column(s) parameter:

  • Horizontal Scroll - by default the width of columns is automatically adjusted, so that all the columns are visible in tables. Often, especially when table window is small, this may result in columns’ widths too narrow to be usable. Enabling Horizontal Scroll overrides this default settings and adds a horizontal scroll-bar on the bottom of the table. As columns are wider they may not all fit in the frame.
  • Pack All Columns - automatically adjusts width of all columns to fit the widest cells’ content.
  • Pack Selected Column - automatically adjusts width of the selected column to fit the widest cell’s contents.
