Font Size

Font size specifies the size of a window element, container, or widget text.

Theme property filter XML code:

Possible values:

0-100 pt

Default value:

specified by SystemTheme.css

Influence and behavior:

You can change the property value in four ways:

• by typing it directly into the field,
• by moving the slider,
• by clicking the up and down arrows of the spinner, or

• by using up, down, right, and left arrow keys on the keyboard:

  

default runtime appearance
property set in theme
resulting runtime appearance

 

If the font size is too large for the text to fit into the element, the text will be cropped:

 

By setting the Bold property to the whole application (= without filters), you change the appearance of window elements like toolbar buttons or messages invoked by fgl_winmessage().

 

At runtime, you can use css styles to change the font size for the element:

 

At runtime, you can use ui method - <var>.FontSize() - to change the font size for the element.

For this purpose, you must

• create a variable of the ui.Font data type,
• apply <var>.FontSize() to this variable, and

• apply the font to the form element by the <var>.setFont() method:

  DEFINE fnt ui.Font

  ...

  LET fnt.FontSize=25

  ...

  CALL lb.SetFont(fnt)

You can find examples of how to use the <var>.FontSize() method here and in the example program.
