Editor Window appears on the right hand side, is the work area available for the TDL programmer. The contents of the file are displayed, added or altered in this window.
Default TDL files (files belonging to the Default TDL project) cannot be altered. They are available only for reference. The Default TDL codes can be used by copying the same to the working project file.
Any file can be opened in the Editor window by double-clicking the particular file in Project Browser or by using the Drag-and-Drop feature, wherein a file can be opened from any location, by using the mouse to drag the file from its location to the Tally.Developer 9 screen. Double-clicking the file (.tdl or .tpj file) launches the file in a new instance of Tally.Developer 9.
The opened files are displayed as Tabs at the bottom of the Editor Window. The position of the Tab Toolbar can be altered, or it can made to disappear at all, from Edit/Style Options in Tools > Preferences . See Changing Editor Preferences for more details.
For more details on the working and features of the Tabs, refer to the topic Working with File Tabs.
