Example
The following examples show how to create font picker and color picker smart controls.
Font |%P=ui_get_font()%.30font;
Color: |%P=ui_select_color(color)%.30color;
Color: |%P=ui_select_color2(color)%.30color;
'Note that a color picker can also be created using the 'C' directive.
Color: |%C%.30color3;
The complete Xdialog syntax is:
ui_dlg_box("Smart Fields",<<%dlg%
Font |%P=ui_get_font()%.30font;
Color: |%P=ui_select_color(color)%.30color;
Color: |%P=ui_select_color2(color2)%.30color2;
Color: |%C%.30color3;
%dlg%)If you are using array variables with square bracket notation, you must escape the trailing "]" bracket with a backslash "\" when the variable is referenced by a control. However, it must not be modified when used inside a function call. For example:
Font: |[%P=ui_get_font("",dat.font[textindex].font)%.30dat.fonttextindex\.font!fontevent_*];
I=$a5_palette%.24dat.rowrow\.color!colorevent_*];See Also
