I have a tgui::Canvas object, to which I connected events using "MousePressed":

auto canvas = tgui::Canvas::create();
canvas->connect("MousePressed", [this]() { /*...*/ });


But it seems the event is only triggered on left mouse click, not on right mouse click.

Is there any way to trigger on both?

Feature requests / setTextureRect on Renderers
« on: 29 August 2019, 12:23:31 »
Could you please add function setTextureRect to Renderers such as ButtonRenderer with the same semantics as sf::Sprite::setTextureRect?
So far, I cannot find a way how to display only a subset of a texture on a button.

Example usage:
auto btn = tgui::Button::create();
btn->getRenderer()->setTexture(myTilesetTexture); // tileset of 16x16 images
btn->getRenderer()->setTextureRect(sf::IntRect(16, 0, 16, 16)); // displaying second image
btn->setSize(16, 16);


Thanks

Help requests / TransparentGrey and BabyBlue themes bug
« on: 19 November 2017, 15:04:54 »
Hi,

I ran into a problem when experimenting with themes bundled with tgui (v0.7). I have copied whole widgets folder to my project's folder. I managed to load theme Black.txt and create ChildWindow from it without any problems (using relative paths). But when I try to load either TransparentGrey or BabyBlue, program throws an exception at the moment where ChildWindow should be created.

The problem is not in paths. I have copied whole contents of TransparentGrey over original content of Black and program crashed too. I restored original Black's contents and program ran just fine. Also I've only copied ChildWindow section from TransparentGrey into Black and overwritten original Black's ChildWindow. That worked. So I assume that somewhere in both TransparentGrey and BabyBlue there is some syntax error.

Help requests / Accessing Picture's underlying sprite
« on: 19 November 2017, 14:58:02 »
Hi,

I am working on a drawing application and I need buttons with icons of various tools (brush, can, etc) that change color based on color selection. So far I am doing it via sf::Sprite that has texture bound to it and calling Sprite::setColor whenever I need to. And I catch the clicks with invisible panel hidden behind it.

But that creates an issue since I have to draw the Sprites after the gui is drawn and thus any elements that possibly can overlap these buttons will be rendered under the Sprites. I was wondering whether I can use something like tgui::Picture to do the job, but unfortunately I can't find a way to access it's underlying sprite (or whatever it uses for rendering).

In the end, Picture renders a texture so there has to be a way to set color to it as well.
Thanks for any tips
