C++ examples for Widget classes

[sebastian.vesenmayer]

Hi community,

the documentation for widget usages with c++ is not very big at the moment and most things I have to try by myself which is very time consuming because there are no examples. I hope this will get better.

Currently I am stuck with WidgetHBox class. Can anybody tell me how to connect WidgetLabels to them with c++ code. A small example would be great.

Thanks Sebastian

Hi Sebastian!

Unfortunately not all types of widgets are currently supplemented with C++ code snippets. All of them are inherited from the Widget class, so you can use addChild() method to add children to some widget.

Here is a simple example demonstrating how to add 2 labels to a horizontal box widget:

// AppWorldLogic.cpp
// incluging the required library
#include <UnigineUserInterface.h>
  /*...*/
  
using namespace Unigine;
GuiPtr gui;
WidgetLabelPtr widget_label1;
WidgetLabelPtr widget_label2;
WidgetHBoxPtr h_box;

  /*...*/
  
int AppWorldLogic::init()
{  
  	/*...*/
	
	// getting a GUI pointer
	gui = Gui::get();
	
	// creating a horizontal box widget and setting up its parameters
	h_box = WidgetHBox::create(gui, 150, 20);
	h_box->setPosition(10, 30);
	h_box->setBackground(1);
	h_box->setColor(Math::vec4(1.0f, 0.0f, 0.0f, 1.0f));

	// creating a label widget and setting a tooltip for it
	widget_label1 = WidgetLabel::create(gui, "Label1");
	widget_label1->setToolTip("I'm Label1 !");

	// creating another label widget and setting a tooltip for it
	widget_label2 = WidgetLabel::create(gui, "Label2");
	widget_label2->setToolTip("I'm Label2 !");

	// adding two labels to the horizontal box
	h_box->addChild(widget_label1->getWidget(), Gui::ALIGN_LEFT);
	h_box->addChild(widget_label2->getWidget(), Gui::ALIGN_LEFT);

	// adding the horizontal box to the GUI
	gui->addChild(h_box->getWidget(), Gui::ALIGN_OVERLAP | Gui::ALIGN_FIXED);
	
	return 1;
}
  
  	/*...*/
  
int AppWorldLogic::shutdown()
{
	// performing some cleanup
	widget_label1.clear();
	widget_label2.clear();
	h_box.clear();
	gui.clear();

	return 1;
}

That's how it looks:

There are code snippets for some of the Widget classes available in the corresponding articles of our documentation (such as WidgetButton, WidgetCheckBox, etc.), as well as a set of examples, that can be found in the C++ API/Widgets samples might come in handy.

The following links may also be useful:

• UI creation example
• Information on UI files

Hope this helps!

Thanks!
