Main Font Size

Controls: Edit Menu >> Start Preferences >> Main Font
Macro: FontMain

All controls and features of the Daqarta application window are proportional to the main font size, including the trace area. (The main title bar and menu bar are not affected. Control dialogs are handled separately by Dialog Font Size.)

Note that this is not the same as resizing the main window by dragging the lower right corner, which changes the window size without changing the size of the controls or trace area.

Daqarta sets the default font size so the main window fills the screen as much as possible. You may want to reduce this value if, for example, you want to move Daqarta's dialogs outside the main window, or have Daqarta open alongside another application.

Note that the trace area is drawn internally at a fixed size corresponding to a font setting of 8, and the resulting image is scaled larger as needed. Trace lines can appear increasingly jagged upon close viewing at higher enlargements.

Note: Changes to this parameter do not take effect until the next Daqarta session.
