KanziStudio工程可執行程序在QNX背景透明詳細配置

 hpp文件 

// 庫文件引入
#ifdef __QNX__
screen_window_t* kzsWindowNativeGetScreenWindow(struct KzsWindowNative* windowNative);
struct KzsDesktopNative* kzsDesktopGetNative(const struct KzsDesktop* desktop);
screen_context_t* kzsDesktopNativeGetScreenContext(struct KzsDesktopNative* desktopNative);
#include <screen/screen.h>
#include <stdio.h>
#include <stdlib.h>
#define EGL_EGLEXT_PROTOTYPES = 1
#define GL_GLEXT_PROTOTYPES = 1
#include <EGL/egl.h>
#include <GLES2/gl2.h>
#include <GLES2/gl2ext.h>
#include <EGL/eglext.h>

#include <kanzi/core.ui/platform/windowing/qnx_screen/kzs_window_native.h>
#include <screen/screen.h>
#endif

 main.cpp中onProjectLoaded()加入 

// 配置可執行程序name=TestDemo
#ifdef __QNX__
        shared_ptr<GlGraphicsOutput> output = dynamic_pointer_cast<GlGraphicsOutput>(getGraphicsOutput());
        KzsDesktopNative* desktopNative = kzsDesktopGetNative(output->getDesktop());
        screen_window_t mainWindow = *kzsWindowNativeGetScreenWindow(kzsWindowGetNative(output->getWindow()));
        char new_name[64] = "TestDemo";
        screen_set_window_property_cv(mainWindow, SCREEN_PROPERTY_ID_STRING, sizeof(new_name), new_name);
        screen_buffer_t screen_buf[2];
        screen_get_window_property_pv(mainWindow, SCREEN_PROPERTY_RENDER_BUFFERS, (void **)screen_buf);
        //KzLogDebug(("set Window Name {}", new_name));
        int rc = screen_post_window(mainWindow, screen_buf[0], 0, NULL, 0);
        if (rc) {
            //KzLogDebug(("Kanzi screen_post_window failed."));
        }
#endif

（方式一）main.cpp中 onConfigure(ApplicationProperties& configuration)加入

virtual void onConfigure(ApplicationProperties& configuration) KZ_OVERRIDE
{
    configuration.binaryName = "demotest.kzb.cfg";
    // 配置可執行程序的groupname
    configuration.defaultWindowProperties.groupName = string("TEST_DEMO");
    configuration.defaultWindowProperties.width = 1280;
    configuration.defaultWindowProperties.height = 720;
    // 配置kanzi工程的rgba參數爲8位使在kzb中設置透明背景生效
    configuration.defaultSurfaceProperties.bitsColorR = 8;
    configuration.defaultSurfaceProperties.bitsColorG = 8;
    configuration.defaultSurfaceProperties.bitsColorB = 8;
    configuration.defaultSurfaceProperties.bitsAlpha = 8;
}

 （方式二）application.cfg中配置

SurfaceBitsRed = 8
SurfaceBitsGreen = 8
SurfaceBitsBlue = 8
SurfaceBitsAlpha = 8
DefaultDisplayIndex = 1

備註：kanzi工程中設置背景色rgba爲0，0，0，0（Screen+RootPage）

application.cfg  example

# An example configuration for a typical high-speed rendering application SurfaceBitsStencil = 1 SurfaceBitsDepthBuffer = 16 SurfaceBitsRed = 5 SurfaceBitsGreen = 6 SurfaceBitsBlue = 5 SurfaceBitsAlpha = 0 SurfaceSamplesAntialiasing = 0     # An example configuration for a high image quality application SurfaceBitsStencil = 8 SurfaceBitsDepthBuffer = 24 SurfaceBitsRed = 8 SurfaceBitsGreen = 8 SurfaceBitsBlue = 8 SurfaceBitsAlpha = 8 SurfaceSamplesAntialiasing = 4

onConfigure()  example

// An example configuration for a typical high-speed rendering application configuration.defaultSurfaceProperties.bitsStencil = 1; configuration.defaultSurfaceProperties.bitsDepthBuffer = 16; configuration.defaultSurfaceProperties.bitsColorR = 5; configuration.defaultSurfaceProperties.bitsColorG = 6; configuration.defaultSurfaceProperties.bitsColorB = 5; configuration.defaultSurfaceProperties.bitsAlpha = 0; configuration.defaultSurfaceProperties.antiAliasing = 0;     // An example configuration for a high image quality application configuration.defaultSurfaceProperties.bitsStencil = 8; configuration.defaultSurfaceProperties.bitsDepthBuffer = 24; configuration.defaultSurfaceProperties.bitsColorR = 8; configuration.defaultSurfaceProperties.bitsColorG = 8; configuration.defaultSurfaceProperties.bitsColorB = 8; configuration.defaultSurfaceProperties.bitsAlpha = 8; configuration.defaultSurfaceProperties.antiAliasing = 4;
