[SOLVED] Error message removing ObjectGui from scene

[david.garcia]

Error message removing ObjectGui from scene.

• Open demo Objects/gui_06.
• Load unigine editor.
• Select any ObjectGui.
• Delete the selected ObjectGui.

"Gui::~Gui(): 1 widgets is not removed from GUI" message appears.

 

Thanks in advance,

Hello,

There are some widgets related to each ObjectGui (WidgetLabel in object/gui_06). So, all related widgets should be removed before ObjectGUI deleting to avoid errors.

 

You can't get access to the widgets from editor, but it can be taken into account in source code.

 

Thanks!

Hello,

 

    Why  ObjectGui desctructor doesn´t remove these widgets that belongs to its Gui object?

 

Thanks!

Deleted widgets can cause a crush because script system will have pointers on them. Moreover script handle manually constructed widgets automatically.

Hi frustum,

 

    Apologizes, but can you explain me "Moreover script handle manually constructed widgets automatically."? 

[frustum]

For example:

Gui gui = engine.getGui();
WidgetLabel label = new WidgetLabel(gui,"Label");
gui.addChild(label,GUI_ALIGN_OVERLAP);

You shouldn't have to delete label manually.

Because the label will be deleted automatically on world quit.

This code is working well for external Gui object.

But for ObjectGui you have to delete label before ObjectGui deletion.
