New page

'''Combo boxes''' consist of two parts. A [[text field]] with an implied [[Q attribute]], and a drop down list that may be used for selection. The Populate process (with the =, + or -) pertains only to the drop down list. INPUT operations pertain only to the text field and respond just like a text field. If Enter is pressed while entering data, then an Enter action is taken. If the mouse is used to select a NEW value, then the trailing interrupt number ([[FKey]]) is applied.

Populate the drop down box:
00100 PRINT FIELDS "row, col,[display-cols/] COMBO data-cols,= [, SELECT] [, Fkey]": mat string$ ! may be =, +,-

Set the text field value:
00200 PRINT FIELDS "row, col,[display-cols/] COMBO data-cols,text-attr [, SELECT] [, Fkey]": string$

Input the text field value (upon selection):
00300 INPUT FIELDS "row, col,[display-cols/] COMBO data-cols, field-input-attr [, SELECT]": string$

Since Combo Boxes are really an enhanced text field, they may be processed with [[RInput Fields]] just like any other text field. This would be done by pre-populating them before issuing the [[Input Fields|Input]] or RInput Fields that groups them in with other text fields.

Combo Boxes are single column only. Use the COMBO drop down character (Q attribute) in conjunction with LIST to effect multi-column dropdowns. Note that such multi-column dropdowns need to be presented in their own child window so they don't destroy underlying controls.

[[FKey]] processing for ComboBoxes is significantly different than for use of the Q character. FKey with COMBO Boxes has no relation to drop down processing. Instead it triggers the specified FKey event when someone makes a selection with the mouse or by pressing ENTER.

If SELECT is specified (as of [[Business Rules!]] version [[4.20]]) when the ComboBox is created it will permit only selection from the drop down list. No text keyboard typing will be permitted. In order to use SELECT, it must be specified when the combo box is created by the populate statement. If SELECT is specified for an already existing COMBO control, a BR error is generated.

The following example demonstrates the use of COMBO boxes. Lines 600 and 700 populate two combo boxes. On line 800, RINPUT FIELDS groups the two COMBO boxes and inputs the selected car and model into the corresponding variables. Line 900 prints results.

====Examples====

=====Example 1=====

00100 print NEWPAGE
00200 dim CAR$(3)*20,MODEL$(6)*20,SELECTEDCAR$*20,SELECTEDMODEL$*20
00300 let CAR$(1)="BMW": let CAR$(2)="Chrysler": let CAR$(3)="Toyota"
00400 let MODEL$(1)="750 IL": let MODEL$(2)="525 CI": let MODEL$(3)="Sebring"
00500 let MODEL$(4)="Concorde": let MODEL$(5)="Corolla": let MODEL$(6)="Camry"
00600 print fields "1,1,20/combo 20,= ": MAT CAR$
00700 print fields "2,1,20/combo 20,= ": MAT MODEL$
00800 rinput fields "1,1,20/combo 20;2,1,20/combo 20": SELECTEDCAR$,SELECTEDMODEL$
00900 print fields "4,1,C 20;4,21,C 20": SELECTEDCAR$,SELECTEDMODEL$
