Property sheet radio buttons
Post by Matt on Oct 16th, 2010, 9:04pm

I'm building a propertysheet which will have dozens of radio buttons. The buttons are in groups of four, but not in group boxes. I can't figure out a way to link them in fours but not with all. I've tried to use the sys comand: SYS "CheckRadioButton", !dlg%, first%, last%, id%, but this doesn't seem to work. I've changed the '!dlg%' to dlg%() and hdlg%, with and without the pling, but nothing. Even putting a groupbox around them doesn't seem to work. Any idea what I'm doing wrong?

Not without seeing your code. The CheckRadioButton API certainly works fine; I use it all the time. Obviously it relies on your radio buttons being given consecutive IDs, but I'm sure you've arranged that.

Since the radiobuttons are not in group boxes, you must ensure that the first (but only the first) button in each group has the WS_GROUP style; but no doubt you've arranged that too.

As it's a property sheet the correct form is:

Code:
SYS "CheckRadioButton", hdlg%(pg%), first%, last%, id%

This is all documented in the BB4W manual.

Here's the main parts taken from the program and put in a test one.
Code:
      REM TEST
      
      INSTALL @lib$+"WINLIB2"
      INSTALL @lib$+"WINLIB4"
      
      datapages%=1
      DIM datapage%(datapages%-1),hdlg%(datapages%-1)
      
      PROC_CONTESTANT_INFO_PROP_SHT_SETUP
      PROC_showpropsheet(contdlg%,hdlg%())
      SYS "CheckRadioButton", hdlg%(0), 25, 28, 25
      G=GET
      PROC_closedialog(contdlg%)
      
      END
      
      
      DEF PROC_CONTESTANT_INFO_PROP_SHT_SETUP
      datapage%(0)=FN_newdialog("Contestant",     0,  0,500,300, 10,1000)
      PROC_static(datapage%(0),"Surname",        10,  5,  6, 43, 12,&2)
      PROC_editbox(datapage%(0),"",              20, 50,  5,100, 12,&1000)
      PROC_groupbox(datapage%(0),"",             30,155,  0,110, 16,0)
      PROC_radiobutton(datapage%(0),"Mr",        25,160,  5, 25, 10,0)
      PROC_radiobutton(datapage%(0),"Mrs",       26,185,  5, 25, 10,0)
      PROC_radiobutton(datapage%(0),"Miss",      27,210,  5, 25, 10,0)
      PROC_radiobutton(datapage%(0),"Ms",        28,235,  5, 25, 10,0)
      PROC_static(datapage%(0),"First Name",     11,  5, 21, 43, 12,&2)
      PROC_editbox(datapage%(0),"",              21, 50, 20,100, 12,&1000)
      PROC_static(datapage%(0),"Membership No.", 12,160, 21, 53, 12,&2)
      PROC_editbox(datapage%(0),"",              22,215, 20,150, 12,&1000)
      PROC_static(datapage%(0),"Address",        13,  5, 36, 43, 12,&2)
      PROC_editbox(datapage%(0),"",              23, 50, 35,315, 12,&1000)
      PROC_radiobutton(datapage%(0),"In WI",     29,340,  5, 25, 10,0)
      
      contdlg% = FN_newpropsheet("Contestant Information",1,0,&80,datapage%())
      ENDPROC

When you click on the 'In WI' button, it deselects the title one.

(FYI. the datapages% is set to 1 but there will be several pages with the many groups of radio buttons on each.)

For a start, a 'lone' radio button makes no sense! Radio buttons must always comes in groups of at least two - that's the whole point of them! It looks to me as though 'In WI' should be a checkbox not a radiobutton.

Secondly, you have not done what I explicitly stated you must do - that is to set the first of each group of radiobuttons to have the WS_GROUP style:

Code:
      WS_GROUP = &20000
      PROC_radiobutton(datapage%(0),"Mr",        25,160,  5, 25, 10, WS_GROUP)
      PROC_radiobutton(datapage%(0),"Mrs",       26,185,  5, 25, 10,0)
      PROC_radiobutton(datapage%(0),"Miss",      27,210,  5, 25, 10,0)
      PROC_radiobutton(datapage%(0),"Ms",        28,235,  5, 25, 10,0)
....
      PROC_radiobutton(datapage%(0),"In WI",     29,340,  5, 25, 10, WS_GROUP)

But it still makes no sense to have a radiobutton on its own.

Richard.

P.S. If you saw Michael Hutton's reply before I deleted it - it's complete nonsense.

You're absolutely right on both counts, Richard. I wasn't doing what you said - mainly due to doing too many things rather than concentrating on the single problem - sorry. And the 'WI' button was only a radio button to show it wasn't working how I wanted it to. It will be a checkbox in the finished program.

Thanks again, Richard.
