Graphics / Global bounds of object inside RenderTexture inside RenderWindow
« on: May 18, 2019, 06:32:46 pm »
Hello 
Usually I like to split my game window (of type RenderWindow) to regions: each region is a RenderTexture which in the end drawn on the main RenderWindow.
By doing this I can split completely the region of the game from the region of the toolbar for instance.
Problem is, when I place a button on the RenderTexture, and I want to check if the button was clicked:
first I'm saving the global coordinates of the mouse click:
And it doesn't work because the m_button.getGlobalBounds() returns the bounds that are relative to the RenderTexture, while m_window.mapPixelToCoords returns coordinates that are relative to the main RenderWindow.
It works only if the button was drawn directly on the main RenderWindow.
Is there a way to convert the mousePos coordinates to be relative to the RenderTexture. Or other way around, to check the GlobalBounds of the button that are relative to the RenderWindow?

const Vector2f mousePos = m_window.mapPixelToCoords({ event.mouseButton.x, event.mouseButton.y });
then I check if the button (of type RectangleShape) contains the position of the click:if (m_button.getGlobalBounds().contains(mousePos))
And it doesn't work because the m_button.getGlobalBounds() returns the bounds that are relative to the RenderTexture, while m_window.mapPixelToCoords returns coordinates that are relative to the main RenderWindow.
