handleslider
« on: 2010-Mar-23 »
In order to get a slider working, I've had to change the code slightly to the following :

Code: GLBasic [Select]
@FUNCTION DDgui_handleslider%: ddgui_vals AS DDGUI_DLG, wdg AS DDGUI_WDG, mx%, my%, b1%, b2%
        wdg.wclicked = b1
        IF b1 = -1
                IF (mx>0 AND my>0 AND mx<wdg.wwidth% AND my<wdg.wheight%)
                        ddgui_vals.focus$ = wdg.wid$
                ENDIF
        ENDIF

        IF ddgui_vals.focus$ = wdg.wid$ AND b1% // MOUSEAXIS(3) // Lclick - set position
                // 0..1
                LOCAL pos = MIN(1.0, MAX(0.0, (mx-5.0)/(wdg.wwidth%-9.0) ))
                // bring in range
                pos = wdg.wminval + pos * (wdg.wmaxval-wdg.wminval)
                // round
                IF wdg.wstep>0
                        LOCAL iSteps% = pos / wdg.wstep + 0.4
                        pos = wdg.wstep * iSteps
                        wdg.wtext$ = pos
                ELSE
                        wdg.wtext$ = FORMAT$(0,2,pos)
                ENDIF

                wdg.wclicked% = TRUE
        ENDIF

        IF b1%=-1 AND ddgui_vals.focus$ = wdg.wid$ THEN ddgui_vals.focus$ = ""
        //IF MOUSEAXIS(3)=0 AND ddgui_vals.focus$ = wdg.wid$ THEN ddgui_vals.focus$ = ""
ENDFUNCTION

I see the problem. I'll fix that, too.

Also, I have the impression that the kerning font printing is too slow. I think about extending the LOADFONT routine with an space_between_characters argument, so you can have font kerning built in or (set that to 0) have monospace texts.

Might be an idea - might be worth looking at Moru's new proportional font system which now also works on the iPhone and is quick.

There's a great impact on using MID$ for every character. But there's only a few characters after all. Not much work to implement, though I think.
