drawRegion

[vad0sss]

Hello, can you add drawRegion from the old j2me platform?

[digitalgust]

ok.let me try.

[digitalgust]

example :

package test;

import org.mini.apploader.GApplication;
import org.mini.gui.*;
import org.mini.gui.event.GActionListener;

import static org.mini.nanovg.Nanovg.*;

/**
 * @author gust
 */
public class MyApp1 extends GApplication {

    GForm form;

    @Override
    public GForm getForm() {

        if (form != null) {
            return form;
        }

        form = new GForm(null);


        GFrame cframe = new GFrame(form, "drawRegion", 0, 0, 500, 300);
        cframe.getView().add(new GCanvas(form, 0, 0, cframe.getView().getW(), cframe.getView().getH()) {
            GImage gimg = GImage.createImageFromJar("/res/test.png");

            public void paint(GGraphics g) {
                g.setClip(0, 0, this.getWidth(), this.getHeight());
                int imgw = gimg.getWidth();
                int imgh = gimg.getHeight();
                int gx = 120, gy = 120, fw = imgw / 2, fh = imgh / 2;
                g.drawRegion(gimg, fw, fh, fw, fh, GGraphics.TRANS_MIRROR_ROT90, gx, gy, GGraphics.HCENTER | GGraphics.VCENTER);
                g.setColor(0xffff00ff);
                g.drawRect(gx - 2, gy - 2, 5, 5);

                int dx = (int) (this.getW() - 100), dy = 0;
                g.drawImage(gimg, dx, dy, imgw, imgh, GGraphics.LEFT | GGraphics.TOP);
            }
        });
        cframe.setFront(true);
        cframe.setClosable(false);
        cframe.align(NVG_ALIGN_CENTER | NVG_ALIGN_MIDDLE);
        form.add(cframe);
        GButton bt = new GButton(form, "exit", 0, 0, 100, 20);
        form.add(bt);
        bt.setActionListener(new GActionListener() {
            @Override
            public void action(GObject gObject) {
                closeApp();
            }
        });
        return form;
    }
}

I'm trying to display the inscription test on the canvas, but something doesn't work for me

[digitalgust]

May you put your code in your github repo?
GViewPort is a scalable containner, so you need not add canvas in a viewport, you can add a GPanel instead.
this.mCanvas = new Game(form, 0, 0, 1, 1); is too small , try to new Game(form, 0, 0, 300, 300)

[digitalgust]

An issue in canvas that setclip is wrong. fix and submited.
Note that you setColor is ARGB data, but not j2me RGB

[vad0sss]

Thanks, setclip solved the problem

[digitalgust]

Graphics is not full j2me implementation , if there are any problem or request please let me know.

[vad0sss]

hi, can you add j2me's Font class analog or android's Paint class analog?

[digitalgust]

add GFont already

[digitalgust]

fixed the SimpleDateFormat.java

@digitalgust
Hello, I did the assembly according to the instructions and everything went without errors. but binary/lib/minijvm_rt.jar file doesn't work. If you replace it from the previous assembly, then it works.
you can send me a link to download it, or the entire project. Thank you

[digitalgust]

1. run /binary/build_jar.sh or build_jar.bat generate minijvm_rt.jar, test on jdk8 or jdk11
2. runt /binary/build_mac_linux.sh or build_winx64.bat generate executable file
3. enter mac_x64 or other platform folder, run test.sh or test.bat
   that's done.

May be the build_jar script can't work on other jdk?

If I run build_jar.bat jdk11 I get an error:
error: option --boot-class-path not allowed with target 11

[digitalgust]

i see. the file GLutil.java is an invalid filename , it should be GLUtil.java , so glfm_gui.jar dose not built, that's it .i will fixed it .

[vad0sss]

I renamed GLUtil.java Ran build_jar.bat and build_winx64.bat everything built without error. When running test.bat got this: image https://ru.files.fm/u/73syxrmyp

[digitalgust]

Ok, I've fixed it on windows platform , It's a bug that load a class file from jar with '\' seaparator, it isn't a valid path string.

[vad0sss]

Great, problem solved. Thank you.
