C++ (Cpp) SetZoomLevel Examples

Example #1

File: TimeLine.cpp Project: rickcowan/xLights

void TimeLine::ZoomIn()
{
    wxString s;
    if(mZoomLevel>0)
    {
        SetZoomLevel(mZoomLevel-1);
    }
}

Example #2

File: browser_window.hpp Project: quartorz/reveal-viewer

	void set_zoom(double percent)
	{
		percent = std::min(std::max(0.2, percent), 5.0);

		auto level = std::log(percent) / std::log(1.2);
		auto host = browser_->GetHost();

		host->SetZoomLevel(level);
		host->GetClient()->OnProcessMessageReceived(browser_, PID_BROWSER, CefProcessMessage::Create(L"RevealViewer.ZoomLevelChanged"));
	}

Example #3

void Waveform::InitializeGLCanvas()
{
    if(!IsShownOnScreen()) return;
    SetCurrentGLContext();
    LOG_GL_ERRORV(glClearColor(0.0f, 0.0f, 0.0f, 0.0f)); // Black Background
    LOG_GL_ERRORV(glDisable(GL_BLEND));
    LOG_GL_ERRORV(glBlendFunc(GL_SRC_ALPHA,GL_ONE_MINUS_SRC_ALPHA));
    LOG_GL_ERRORV(glClear(GL_COLOR_BUFFER_BIT));
    prepare2DViewport(0,0,mWindowWidth, mWindowHeight);
    mIsInitialized = true;
    SetZoomLevel(mZoomLevel);
}

Example #4

File: TimeLine.cpp Project: rickcowan/xLights

void TimeLine::ZoomOut()
{
    if(mZoomLevel<mMaxZoomLevel)
    {
        SetZoomLevel(mZoomLevel+1);

            RaiseChangeTimeline();
        }
    }
