drawString() is painting in BGImage

[yafy]

hi folks,

my sonyericcson emulator's width:176 and height:220.
Im having one image with same height but double the width.

so,
g.drawImage(transparentImage,0,0,g.TOP|g.LEFT);

will display only the first half of the img.

when i press any key , i want to show the second hidden part of the same image so that it creates an illusion of moving.

when i used,
g.translate(-175,0);

its suddenly moving to second part but not creates any illusion of movement.

before painting transparentImage i ve already painted BGImage.

now if i use

g.translate(-175,0);
g.drawString("painting",8,96,g.TOP|g.LEFT);

the "painting " is painted in the BGImage and not on top of transparentImage.

Please suggest....

1. how to move the img gradually
2. how to drawstring on top of that moved img


Thanks in advance

Hi,
instead of hardcoding the values for drawing the image just use variables that increases or decreases their values as the key is pressed.

thanks for reply...

i actually used the following code below,

for(int i=0;i<-175;i--){
g.translate(i,0);
try{
t.sleep(500);
}catch(Exception e){}
g.drawImage(interfaceImage,i,0,g.TOP|g.LEFT);

}

but its not working.Am i correct or how can i modify my code...
plz suggest.

Hi Yafy,

I think here is a problem in ur code.
where have u written the code.
does it execute the painting part.ie: does it call the repaint() & serviceRepaints() in the for loop itself ?
For every g.translate(i,0); u have to call repaint or servicerepaints()


If possible Can u please post the whole sample code

hi

Quote: "For every g.translate(i,0); u have to call repaint or servicerepaints()"
thats also not working.

Below is my paint :


public void paint(Graphics g)
{

System.out.println("enter into paint.....");

int w = g.getClipWidth();
int h = g.getClipHeight();

// wordWrap = new WordWrap(Font.getFont( Font.FACE_PROPORTIONAL,
// Font.STYLE_BOLD | Font.STYLE_PLAIN, Font.SIZE_SMALL ),QStr,w);

g.setFont( Font.getFont( Font.FACE_PROPORTIONAL,
Font.STYLE_BOLD | Font.STYLE_PLAIN, Font.SIZE_SMALL ) );


g.setGrayScale(255);

g.drawImage(BackgroundImage,0,0,g.TOP|g.LEFT);

g.drawImage(questionBarImage,0,0,g.TOP|g.LEFT);
g.setClip(0, 0, interfaceImage.getWidth(), interfaceImage.getHeight());

if(translateFlag == 1 ){

for(int i=0;i<-175;i--){
g.translate(i,0);
repaint();
g.drawImage(interfaceImage,i,0,g.TOP|g.LEFT);
try{
t.sleep(500);
}catch(Exception e){}

}

g.drawImage(okButtonImage,175,210,g.TOP|g.LEFT);
g.drawImage(passButtonImage,315,210,g.TOP|g.LEFT);

g.drawString(A1Str,215,86,g.TOP|g.LEFT);
g.drawString(A2Str,215,120,g.TOP|g.LEFT);
g.drawString(A3Str,215,154,g.TOP|g.LEFT);
g.drawString(A4Str,215,188,g.TOP|g.LEFT);
translateFlag = 0;
}else {}
if(playFlag == 1){
playFlag = 0;
switch(spinMidlet.randomCategory)
{

case 1:
translateFlag = 1;

g.drawImage(interfaceImage,0,0,g.TOP|g.LEFT);//first part of img is painted here correcty
g.drawImage(generalImage,75,5,g.TOP|g.LEFT);
//after painting generalimg i want to move the translateimg.

repaint();break;
case 2:

..........

}
}}
else{
g.drawImage(interfaceImage,0,0,g.TOP|g.LEFT);


}
g.drawImage(playButtonImage,10,210,g.TOP|g.LEFT);

}//end paint


ro be clear ,when i press play button (playFlag=1) generalimg is painted on interfaceimg and set translateflag =1 .after this only i want to translate(move) interfaceimg .

thanks

Hi Yafy,
Please use the paint method only for painting.Please avoid the logic and other non-painting methods from the paint method.
