slibio / slib Goto Github PK

Android:
error info:java.io.FileNotFoundException.

IOS:
It's OK.

For example:
Some words under a icon/image in center of button.

m_bButton2->setText("Test Title");
m_bButton2->setMultiLine(true);
m_bButton2->setMargin(30, 5, 5, 5);
m_bButton2->setSize(this->dprToPx(150), this->dprToPx(90));
m_bButton2->setBorder(false);
m_bButton2->setTextColor(slib::Color(54,142,244,255));
m_bButton2->setTextAlignment(slib::Alignment::BottomCenter);
m_bButton2->setIconMargin(10, 10, 10, 0);
m_bButton2->setIconSize(this->dprToPx(50), this->dprToPx(50));
m_bButton2->setIconAlignment(slib::Alignment::TopCenter);
m_bButton2->setIcon(slib::PlatformDrawable::loadFromAsset("images/images/homebg1.png"));

now,I can't set background's alpha by setAlpha();
eg.
m_view = new View;
m_view->setWidthFilling();
m_view->setHeight(150);//It's px? I advise to use dp.
m_view->setTop(0);
m_view->setBorderColor(slib::Color::Red); // test Color
m_view->setBorderWidth(2);
//m_view->setAlwaysOnDrawBackground(true);
m_view->setBackgroundColor(slib::Color::Blue);
m_view->setAlpha(0.8);

A bug in ChromiumView on mac.
I was added ChromiumView into linear in sapp.
but webview can not show in window,untill I have been resized the window.

It's normal without sapp(example project).
[SAPP]

[CPP]

void MainWindow::onCreate()
{
Ref m_webView;
this->setResizable(true);
m_webView = new ChromiumView;
m_webView->setWidthFilling();
m_webView->setHeightFilling();
m_webView->loadURL("https://bing.com");
mainLinear->addChild(m_webView);
}

the webview is null when open a url/page.
code:

m_webView = new WebView();
m_webView->setWidthFilling();
m_webView->setHeightFilling();

m_webView->loadURL("http://mozilla.org/MPL/2.0/");

Console::println("Error:%s",m_webView->getErrorMessage());

addViewToContent(m_webView);

Keyboard cover up the textbox some times.
Is there a better solution?

How to set the mainwindows can resizeable. In macos/win32/linux project.

Among View attributes, it'll be better to define cornerRound to specify round size at corners.
It will be useful to create round buttons.

In this case, there will be conflict between boundShape attribute.
boundShape can be one of rectangle, ellipseor roundRect.
My request is related to roundRect but more edge-case.

So I suggest following forms of solution based on removing boundShape.

<View
   ...
   width="dimenWidth"
   height="dimenHeight"
   cornerRound="dimenCorner"
   ...
/>

Let's assume that dimenWidth > dimenHeight.

• if dimenCorner=0, same result of boundShape=rectangle.
• if dimenCorner<dimenHeight/2, similar to boundShape=roundRect but more accurate.
• if dimenHeight/2<=dimenCorner<dimenWidth/2, round sides but linear top/bottom lines.
• otherwise, same result of boundShape=ellipse.

How to use dp(not px) like android in setWidth/setHeight...?

Would it be possible to have any example on how to use SLib for iOS/Android via a tableview/list sample app ?

An extra null pointer check is not needed in functions like the following.

• _Gdiplus_BrushObject
• _Win32_FontObject
• ScopedPtr::release

How to show the example of SLide Layouts?

very nice lib。

How to create a new project in SLIBIO.
Thanks.

I try to use:
m_mediaplayer = new MediaPlayer;

then,Xcode show me:"Allocating an object of abstract class type 'slib::MediaPlayer'"

Has SLib been used in production ? If yes, for which platform and in which context ?

B.

When I use the aspect ratio mode for layouting and wrapping, it doesn't work properly for linear view.

		backgroundScale='cover'

				width='15%sw'
				centerHorizontal='true'/>
			
			<label text='Welcome to SLib.io'

How to capture the LoadUrl completion event of imageView?

Me again.
As I am waiting for the iOS example, I've been trying to at least test the Android part as I saw there was a JNI example in the examples folder.
So the basic example does run. But as soon as I try to use the SLibActivity on the Java side I end up with the error specified in the title
Here is the full bug report:

What steps will reproduce the problem?

1. Build and run the JNI example
2. JNI example runs without any error
3. In MainActivity, add

Intent intent = new Intent(this, VideoActivity.class);
this.startActivity(intent);

to onCreate

with VideoActivity as follows:

public class VideoActivity extends SlibActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        Log.d("VideoActivity", "onCreate");

    }
}

4. The app crashes

What is the expected result?

The app should not crash

What do you see instead?

1. The app crashes with:

What version of the product are you using? On what operating system?

Version v0.1.4 - Android 7.0

Please provide any additional information below.

1. I am not sure what is going on, why the linking error happens as thenative-lib.so gets loaded properly but then at runtime, calling Android.nativeOnCreateActivity crashes

Hope you will be able to help out, I'm just trying to get a camera feed.

The project "CameraView" can not show anything from camera in Android.
And the same time,function "addViewToContent" can not show any view in Android.

hi, thanks for so nice lib!!!
i have some suggest about headers.

1. rename the root dir "inc" to "include"
2. change the include rule "../../../inc/slib/xxx/xxx.h" to "slib/xxx/xxx.h"
   do it to all header and src,just as google c++ guide.

example: SLib/src/slib/core/base.cpp
#include "../../../inc/slib/core/base.h" ==> #include "slib/core/base.h"

example:SLib/inc/slib/core/base.h
#include "definition.h" ==> #include "slib/core/definition.h"

The C++ Standard, [reserved.names] [ISO/IEC 14882-2014], specifies the following rules regarding reserved names:

• ...
• Each name that contains a double underscore __ or begins with an underscore followed by an uppercase letter is reserved to the implementation for any use.
• Each name that begins with an underscore is reserved to the implementation for use as a name in the global namespace.
• ...

How to add a new font in slib?

Is it possible to support multi-language?
For example, native Android provides strings-xx.xml file inside value... and all values defined in this file are used for localization.
In other words, we can get different texts according to language preference by using just one id.
This is valid in iOS even if the method is different.

Is it possible such usage in SLib? If not, this is elementary requirement, I think.

IOS:OK
Android:Error

I/System: Daemon delayGCRequest, sDelayGCRequest=false, delay=true, sPendingGCRequest=false
I/Console: Width:1080
PPI:4294967295(Error value)

code:
Console::print("PPI:%d",DeviceInformation::getDevicePPI());

This is issued from #2

In following example, maybe the dev needs to track while animating, how much the value has been changed as the time being.

Ref<Animation> animation = view->createTranslateAnimationTo(Vector2(300, 300), 3);
animation->setRepeatCount(5);
animation->start();

So, how about following solution?

Ref<Animation> animation = view->createTranslateAnimationTo(Vector2(300, 300), 3);
animation->setRepeatCount(5);

// suggestion //////
animation->setTracker([](deltaTime, state) {
    // deltaTime is 0-based and limited to 3s x 5(repeat)
    // state is related to Vector2(300,300)
    do_some(deltaTime, state);
}); 
/////////////////////////

animation->start();

<image
    name='img1'
    src='@drawable/ui_img1'
    scale='contain'
    width='40%sw'
    height='40%sh'
    centerHorizontal='true'
    top='15%sh'
/>
...
<image
    name='img2'
    src='@drawable/ui_img2'
    scale='contain'
    width='40%sw'
    height='40%sh'
    centerHorizontal='true'
    top='15%sh'
/>

Here, it's not convenient to write 40%sp every time and will be more annoying for update/revision.
Such problems happen in working with values like

• dimension
• color
• number
• animation
• shape

There's already string value implemented in desirable way.

I'm reading document, but I think it would be good if you can change alignBottom to alignParentBottom.
It's a bit complicated, because if you didn't provided screenshot, I couldn't notice that it's
a layout_gravity option.
I thought it's a gravity option at the first time before I check the screenshot.
