Came across a weird problem with the transparency the same code produces different results in android vs windows. I’m coding some themes for the windows and would like to include transparency. It works in windows, but not in android.
Ive linked the sketchfiles and all required jars on github.
and have extended the window class so I could try to debug the issue.
class wnd extends Window{
//applet = b;
wnd(float xx,float yy,float ww,float hh,String dir,BMS bms){
//super(b);
x = xx;
y = yy;
w = ww;
h = hh;
bw = w;
bh = h;
Bms = bms;
applet = bms.applet;
theme = Bms.theme;
list = fileUtils.listFileNames(dir);
link = dir;
currentp = dir;
initqNav();
initGrid();
//cols = 10;
println(buttons.size(),cols);
canvas1 = applet.createGraphics((int)w-10,(int)(rowheight*3.5));
canvas2 = applet.createGraphics((int)w-10,(int)(rowheight*3.5));
};
wnd(boolean k){
initqNav();
};
public void displayGrid(){
//
h = (7+1) * 50;
//if(mousePressed)
open = true;
Slider s = null;
if(sliders.get(0)!=null)s = sliders.get(0);
s.h = h;
s.setRadius(0,0,20,0);
if(toggle||applet.frameCount==0) {
open = true;
}else {
open = false;
}
if(close){
toggle = false;
open = false;
close = false;
}
if(open||firstRun||buttonHover) {
canvas1.beginDraw();
canvas1.background(255,0);
//canvas1.fill(theme.windowfillcol,theme.windowtransparency/40);
canvas1.noStroke();
//if(firstRun||buttonHover)canvas1.rect(0,0,w,h,r1,r2,r3,r4);
}
if(open){
Window w2 = windows.get(windows.size()-1);
mouse = getMouse();
float ay = 70;
if(w2!=null&&!fileDir.toggle) {
fileDir.label = w2.link;
}
//else fileDir.textBox = "";
fileName.setPos(x+20,y+h-ay);
fileDir.setPos(x+90,y - 45);
select.setPos(fileName.x+20+fileName.w,y+h-ay);
drawBorder();
drawNav();
// if(getClose())close = true;
//id();
drawRapidOptions();
select.draw();
select.toggleAll();
select.toggle(0,this,"close");
select.toggle(1,this,"close");
drawScrollbar();
gridlogic();
grid();
fileName.draw();
fileDir.draw();
if(open||firstRun) {
canvas1.endDraw();
update = false;
firstRun = false;
}
}
if(open)applet.image(canvas1,x,y);
};
public void grid(){
Window w2 = windows.get(windows.size()-1);
Slider s = sliders.get(0);
// s.mouseFunctions();
// s.set(0,2000);
mouse = getMouse();
mouse.y+=20-s.value;
counter = 0;
// applet.println("window",y,h);
int miny = (int)(s.value/rowheight);
// applet.println("window",miny,rows);
int maxy = miny+5;
if(true) {
for(int i=0;i<7;i++){
maxy = miny+5;
for(int j=0;j<10;j++){
int pos = j+i*cols;
Button b = null;
if(pos<w2.buttonGrid.size()){
b = w2.buttonGrid.get(pos);
Button b1 = w2.buttons.get(pos);
b.visible = false;
// applet.println(b.tsize);
// if(pos==0)
//applet.println(pos,i,j);
if(w2.init)b.setPos( 10 + colwidth * j,
10 + (rowheight+b.tsize) * i);
b.y = b.by - s.value+20;
b.mouse = mouse;
//b.highlight(mouse);
b.draw(canvas1);
b.textbtm = true;
b.yoff = -20;
b.parentCanvas = true;
if(!b.textcheck)b.labelcheck(colwidth);
//
boolean k = b.pos(mouse);
b.set = true;
//if(b.visible)
if(k&&b.submenu!=null&&track.size()<1){
int size = currentp.length();
if(currentp.charAt(size-1)!='\\')currentp += "\\";
currentl = currentp + b.blabel;
}
else if(k&&b.submenu==null){
int size = currentp.length();
if(currentp.charAt(size-1)!='\\')currentp += "\\";
currentf = currentp + b.blabel;
}
if(k&&theme.dclick&&b1.submenu!=null&&!smdown&&track.size()<1){
int size = currentp.length();
if(currentp.charAt(size-1)!='\\')currentp += "\\";
back = currentp;
currentp += b.blabel;
forward = currentp;
Window w1 = new Window(w2.x+200,w2.y,w,h,currentp,Bms);
windows.add(w1);
windex = 0;
s.value = 0;
s.valuex = 0;
wid = windows.size()-1;
smdown = true;
currentFolder = currentf;
}
else if(k&&theme.dclick&&b1.submenu==null&&!smdown&&track.size()<1){
int size = currentp.length();
if(currentp.charAt(size-1)!='\\')currentp += "\\";
String file = currentp + b.blabel;
currentf = file;
currentLink = currentf;
//if(launchable)launch(file);
smdown = true;
}
if(k)counter++;
// // rect
}
}}
w2.init = true;
}
buttonHover = counter>0;
if(!applet.mousePressed)smdown = false;
};
};
this is where the problem occurs
if(open||firstRun||buttonHover) {
canvas1.beginDraw();
canvas1.background(255,0);
//canvas1.fill(theme.windowfillcol,theme.windowtransparency/40);
canvas1.noStroke();
//if(firstRun||buttonHover)canvas1.rect(0,0,w,h,r1,r2,r3,r4);
}
I’m guessing this might be a complex issue to solve, if there is no solution I’ll have to remove the transparency for android, but it just seems a shame.
android
windows
as you can see yes there is transparency in android, but each time i scroll it stacks on top of the previous draw, again the windows version doesnt have this problem.
