Hmmmm....looks a lot like my VQB_Frame command!

I did something very similar to Fellippe's "box" subroutine for making buttons in my star system simulator. SierraKen's calculator buttons inspired me to add a "beveling" SUB to add some 3D pop to them, also similar to the frame examples above. I also made it so that the button label would show any associated hotkeys in a highlight color. Easy to change the position & parameters of the buttons.

All that's required is to call:
Con_Blok x position, y position, width, height, button label, hotkey position, button color

Code: QB64: [Select]

A& = _NEWIMAGE(600, 400, 32)
SCREEN A&
'DIM SHARED f&
'f& = _LOADFONT("c:\windows\fonts\arialbd.ttf", 16, "monospace")

Con_Blok 300, 150, 80, 48, "Fetch", 1, &HFF04500FF
Con_Blok 500, 320, 80, 48, "Roll", 1, &HFFFF00FF
 
 
 
SUB Con_Blok (xpos AS INTEGER, ypos AS INTEGER, xsiz AS INTEGER, ysiz AS INTEGER, label AS STRING, high AS INTEGER, col AS _UNSIGNED LONG)
 
    'Create control block
    CN& = _NEWIMAGE(xsiz, ysiz, 32)

    x = LEN(label)
    IF f& > 0 THEN '                                            if font is available
        sx = (xsiz / 2) - (x * _FONTWIDTH(f&)) / 3
        sy = ysiz / 2 - 6
        _FONT f&
    ELSE '                                                      if not

            COLOR &HFFFF0000

        END IF
        IF col = &HFFC80000 THEN COLOR 15

@Unseen Machine yeah, yours look like 3D pads sticking up from a surface. You might like the fill triangle I used for thic line, no PAINT so no possible interference by other objects.

@OldMoses yeah I like those buttons too.

bplus · « **Reply #18 on:** September 27, 2020, 04:48:34 pm »

@carloscordeiro

Seeing as you've just begun using graphics screens you might like the QB4.5 colors used in SCREEN 12 converted to _RGB32() colors for your custom designed screen made with _NEWIMAGE

You can tinker with the numbers but I use an qb~& FUNCTION for 0-15 colors converted to 32 bit EGB

Code: QB64: [Select]

FUNCTION qb~& (n AS INTEGER)
    SELECT CASE n
        CASE 0: qb~& = &HFF000000
        CASE 1: qb~& = &HFF000088
        CASE 2: qb~& = &HFF008800
        CASE 3: qb~& = &HFF008888
        CASE 4: qb~& = &HFF880000
        CASE 5: qb~& = &HFF880088
        CASE 6: qb~& = &HFF888800
        CASE 7: qb~& = &HFFCCCCCC
        CASE 8: qb~& = &HFF888888
        CASE 9: qb~& = &HFF0000FF
        CASE 10: qb~& = &HFF00FF00
        CASE 11: qb~& = &HFF00FFFF
        CASE 12: qb~& = &HFFFF0000
        CASE 13: qb~& = &HFFFF00FF
        CASE 14: qb~& = &HFFFFFF00
        CASE 15: qb~& = &HFFFFFFFF
    END SELECT
END FUNCTION
 

If I want red 12, I use qb~&(12), blue qb~&(9)....

the ~& are the suffix to _UNSIGNED LONG the best type to use for 32 bit colors.

So to PRINT s$ in red on black:
COLOR qb~&(12), qb~&(0)
PRINT s$

What is also cool is you can adjust the colors to your liking! So you can get a real orange and green.

I will keep the two simpler ones for the box I want.

OldMoses:

Code: QB64: [Select]
SCREEN 12
thick = 5
FOR x = 0 TO thick
LINE (6 + x, 5 + x)-(632 - x, 462 - x), 11, B ' box or frame
'LINE (7, 6)-(631, 461), 11, B 'Slightly thicker lines
LINE (6 + x, 5 + x)-(632 - x, 50 - x), 11, B
NEXT x

And Felipe:

Código: QB64 : [Selecionar]
TELA _NOVAIMAGEM ( 800 , 600 , 32 )
caixa 0 , 0 , 200 , 130 , 10 , _RGB32 ( 183 , 133 , 33 )
SUB box ( x , y , w , h , espessura , a cor AS _UNSIGNED LONG )
LINE ( x , y ) - STEP ( w , h ) , theColor , BF
LINHA ( x + espessura , y + espessura ) - PASSO ( w - espessura * 2 , h - espessura * 2 ) , _BACKGROUNDCOLOR , BF
END SUB

Felipe's line code is great.
Simple and with few lines.

Thank you all

Carlos

Hi
I must admit that all you guys are very active and have so fantastic ideas to develope the request of carloscordeiro!
I find very interesting your solutions, only Bplus have posted nothing!
However I post my raw two cents :

Code: QB64: [Select]

SCREEN _NEWIMAGE(800, 600, 32)
Makeframe 100, 300, 500, 350, 5, _RGB32(255, 0, 0)
Makeframe 70, 400, 700, 10, 5, _RGB32(0, 150, 0)
Makeframe 150, 400, 170, 10, 5, _RGB32(50, 50, 50)
MakeLine 10, 300, 700, 400, 5, _RGB32(10, 100, 255)
MakeLine 100, 200, 500, 400, 4, _RGB32(100, 10, 55)
END
 
SUB Makeframe (xStart, yStart, xEnd, yEnd, Thik, C AS _UNSIGNED LONG)
    IF xStart > xEnd THEN SWAP xStart, xEnd
    IF yStart > yEnd THEN SWAP yStart, yEnd
    LINE (xStart, yStart)-(xEnd, yEnd), C, B
    LINE (xStart + Thik, yStart + Thik)-(xEnd - Thik, yEnd - Thik), C, B
    PAINT (xStart + INT(Thik / 2), yStart + INT(Thik / 2)), C, POINT(xStart, yStart)
END SUB
 
SUB MakeLine (xStart, yStart, xEnd, yEnd, Thik, C AS _UNSIGNED LONG)
    LINE (xStart, yStart)-(xEnd, yEnd), C
    LINE (xStart, yStart + Thik)-(xEnd, yEnd + Thik), C
    LINE (xStart, yStart)-(xStart, yStart + Thik), C
    LINE (xEnd, yEnd)-(xEnd, yEnd + Thik), C
    PAINT (xStart + INT(Thik / 2), yStart + INT(Thik / 2)), C, POINT(xStart, yStart)
END SUB
 
SUB grid (xMin, yMin, xMax, yMax, xDelta, yDelta, C AS _UNSIGNED LONG)
    'this sub creates a costumizable grid on the screen
    FOR a = xMin TO xMax STEP xDelta
        LINE (a, yMin)-(a, yMax), C
    NEXT
    FOR a = yMin TO yMax STEP yDelta
        LINE (xMin, a)-(xMax, a), C
    NEXT
END SUB

@carloscordeiro
I must point out that with Draw you can increase only one dimension of the line that you draw...
see here this code show this concept.

Code: QB64: [Select]

SCREEN _NEWIMAGE(800, 600, 32)
grid 1, 800, 10, 1, 600, 5, _RGB32(0, 155, 0)
LINE (100, 100)-(500, 100), _RGB32(255, 0, 0)
DRAW "s16bm100,200m500,200"
DRAW "s16bm100,300r100" ' the effect is on the direction of movement s4 = 1 pixel
DRAW "s32bm100,350r50" ' s8= 2 pixels, s16 = 4 pixels, s32 = 8 pixels
LINE (100, 400)-(500, 400), _RGB32(255, 0, 0)
END
 
SUB grid (xMin, yMin, xMax, yMax, xDelta, yDelta, C AS _UNSIGNED LONG)
    'this sub creates a costumizable grid on the screen
    FOR a = xMin TO xMax STEP xDelta
        LINE (a, yMin)-(a, yMax), C
    NEXT
    FOR a = yMin TO yMax STEP yDelta
        LINE (xMin, a)-(xMax, a), C
    NEXT
END SUB

@carloscordeiro

All SUBs and FUNCTIONs have to be listed after Main code, data statements and or GOSUBS from main code.

Should be OK to cut and paste the SUB lower or last in code.

Caution: Fellippe's box blacks out the interior space but if you use it first and then fill in the space with text you should be OK.

Old Moses has just what you would like I think, he did it without SUBs or FUNCTIONs which I don't think you are use to yet.
