meue selection

Hello, below see a simple menue, that works fine. My questions:

1. Is there a possibility for additional line selections by a simple left mouse click

2. Is there a possibility for additional line selections by pressing a underlined or collored char

3. When the first line is highlighted and you press the 'cursor up' key the highlighted line does not change to the last line. When the last line is highlighted and you press the 'cursor down' key the highlighted line does not change to the first line. Is there a possibility to change this?

You have given a constant value of 1 for the selected item in the list, use a variable instead and put that in a common block to make it available to the callback routine. You can change the selection by changing the value by another function and call window_update@. For multiple selections, use %ms and change iselect to an array. Regards Ian

Dear Ian, thank you very much for your prompt help, now I understand it and the code below works fine. But still 2 questions:

• is it possible to youse a no_border function, the %co[no_data_border] does'nt work?
• is it possible to center the box in the outer border?

Thank you very much.

No - that only seems to apply to %rd, %rf, %rs, %re, %el Centring - yes see below plus some tidy-up of the code arrays may be initialised without a do loop, window caption added, background set to users current windows default. The use of the cursor keys seems to partially defeat the use of a %ms, a %ls would be satisfactory and sel would be a single value, in which case the cursor control would be better as: cursor down sel = mod(sel,selmax)+1 cursor up sel = mod(sel-selmax-1,selmax)+selmax

Dear Ian, thank you very much for your help. It's only a pity that the no_border or no_frame option does'nt work.

Best Regards Bartl

Yes, you are right. It seems a shame that Clearwin+ does not implement this function on all controls which have an outline for consistency and completeness. Ian

My question is not directly related to the original one above. However, I would like to ask something on the value (or status) of the variable sel. I slightly adapted the example and think you could help me. My question: 1.) is the value of sel automatically updated after a selection in the combo box or 2.) are the some cases where I explicitly have to inquire for it?

When is it necessary to use the LISTBOX_ITEM_SELECTED parameter in clearwin_info@).

According to the documentation:

LISTBOX_ITEM_SELECTED Used in a call-back function for a list box. Returns 1 if the item was “selected” by double clicking on an item in the extended list; returns zero if the item was “moved to” by using a single click.

So this will give a value for a double click only, else it will be zero - your callback can ignore zero values. The value of sel will always be the selected one whether single or double clicked. To detect a double click without this function and using the value of sel, the 'Callback_reason' would need to be checked using CLEARWIN_STRING@. Regards Ian
