Bitmap	C	Optional. The name of a bitmap to put at the right edge of the control.
Width	N	The width of the control.
Varname	A	The variable that receives the return value from the function.

Description

Alpha Five allows you to define your own smart fields, which look at drop-down edit combo boxes.

Type	Example
Color	[%P=ui_select_color(Color_Variable)] [%P=ui_select_color2(Color_Variable)]
Date	[%P=popup.calendar(dtoc(Date_Variable));I=popup.calendar%.30Date_Variable]
Field	[%P=ui_get_fieldname(Table_Name))%.30Field_Variable]
File	[%fFile_Type_Filter%.50Filename_Variable]
Filter	[%P=ui_get_filter(Title, Prompt, Default_Filter, Table)%.50Filter_Variable]
Font	[%P=ui_get_font(Title, Font_Variable)%.30Font_Variable]
Number	[%P=popup.calculator(Number_Variable);I=popup.calculator%.30Number_Variable] [%sLow_Value,High_Value%.30Number_Variable]
Order	[%P=ui_get_order(Title, Prompt, Default_Order, Table)%.50Order_Variable]
Path	[%p=ui_get_path(Title, Default_Drive, Default_Path);I=$a5_folder%.50Path_Variable]

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(dat.row[row].color)]; ' drop down list of names

Color: |[%P=ui_select_color2(dat.row[row].color)]; ' palette display

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.font[textindex\].font!fontevent_*];

I=$a5_palette%.24dat.row[row\].color!colorevent_*];
