How to disable the title bar of a window (undecorated window)

effect (the grey rectangle is the openframeworks window):

This tip depends on the renderer you are using! As i'm running linux (on a crappy computer, not sure it is valid for any linux-hardware rig), i had to modify the method setup in [OF_ROOT]/lib/openFrameworks/app/ofAppGLFWWindow.cpp.

ofAppGLFWWindow::setup(const ofGLFWWindowSettings & _settings) {
	
	...
	glfwDefaultWindowHints();
	glfwWindowHint(GLFW_VISIBLE, GL_FALSE);

Then you have to recompile OF. Once again, i'm running linux so i just to do:

$ [OF_ROOT]/scripts/linux/./compileOF.sh

And clean and recompile any app using OF.

All methods to manipulate the window trough C++ are listed in [OF_ROOT]/lib/openFrameworks/app/ofAppRunner.cpp.

bool ofDoesHWOrientation();
ofPoint ofGetWindowSize();
ofRectangle ofGetWindowRect()
ofAppBaseWindow * ofGetWindowPtr();
void ofSetWindowPosition(int x, int y);
void ofSetWindowShape(int width, int height);
void ofSetWindowTitle(string title);
void ofEnableSetupScreen();
void ofDisableSetupScreen();
void ofSetFullscreen(bool fullscreen);
void ofToggleFullscreen();

You can also get the native objects, depending on the OS:

Display* ofGetX11Display();
Window  ofGetX11Window();

Tested on linux mint 18.3 & of v0.9.8
