Examples Window Size/Resolution Issue

[blazer2k1]

When changing the width and height to any size say, 1024x768 in the Examples, particularly the C99 Example 25. The resolution remains the same at 1280x720 when compiled.

int32_t _main_(int32_t _argc, char** _argv)
{
	uint32_t width  = 1024; // This does nothing
	uint32_t height = 768;  // still at 1280x720
	uint32_t debug  = BGFX_DEBUG_TEXT;
	uint32_t reset  = BGFX_RESET_VSYNC;

This is expected... This example is there to demonstrate bgfx C99 API and nothing else. Example harness doesn't have C99 implementation therefore not all features are available in this example.

Hi @bkaradzic , It is also for other examples like the HelloWorld cpp example. Just starting out bgfx, so how do I set the width and height of the window? Overriding the below _width and _height does nothing.

class ExampleHelloWorld : public entry::AppI
{
public:
	ExampleHelloWorld(const char* _name, const char* _description, const char* _url)
		: entry::AppI(_name, _description, _url)
	{
	}

	void init(int32_t _argc, const char* const* _argv, uint32_t _width, uint32_t _height) override
	{
		Args args(_argc, _argv);

		m_width  = _width;
		m_height = _height;

bgfx doesn't deal with window size... What is setting here is backbuffer size:

		m_width  = _width;
		m_height = _height;

If you want to change example harness window size programmatically you need to use entry::setWindowSize function:

bgfx/examples/common/entry/entry.h

Lines 279 to 280 in e33efb8

	///
	void setWindowSize(WindowHandle _handle, uint32_t _width, uint32_t _height);

Thanks, this is what I'm looking for!

@bkaradzic, I tried modifying the example but no effect:

m_width = 800;
m_height = 600;
init.platformData.nwh  = entry::getNativeWindowHandle(entry::kDefaultWindowHandle);
init.platformData.ndt  = entry::getNativeDisplayHandle();
entry::setWindowSize(entry::kDefaultWindowHandle, m_width, m_height);
init.resolution.width  = m_width;
init.resolution.height = m_height;
init.resolution.reset  = m_reset;
bgfx::init(init);

same issue that was not answered here: #1203 (comment)

This is what I get, the buffer has been resized, but window size is still 1280x720

It should be fixed: 4f3ce6a

Works great!
