Widget Offset

How can I set the offset between widgets in a grid?
auto grid = tgui::Grid::create();
grid->setPosition(400, 200);
for (int i = 0; i < 5; ++i)
for (int j = 0; j < 5; ++j) {
auto button = tgui::Button::create("Hi");
button->setSize(40, 40);
grid->addWidget(button, i, j);
grid->setSize(200, 200); // I have to make sure that there is free space between the buttons

I can get the offset values for the widget from grid->getWidgetOffset(); But how do I change them?
I need to achieve an offset of 2 pixels between the buttons and each time it is inconvenient to select the grid size.


You don't actually have to set the grid size. If you call grid->setSize then you let the gui calculate the offsets to fill the size, while you want to manually set offsets. The addWidget function takes 5 parameters in total, the 4th one being a border to place around the widget (I guess this should probably be renamed to "padding" instead of "border"). So the following will add a button with 2 pixels on each side:
Code (cpp) Select
grid->addWidget(button, i, j, tgui::Padding(2));

You might want to choose the padding differently, because like this you get 4 pixels between each widget (since each has a 2 pixel padding around it). Also the Padding constructor takes more parameters if not all sides need to have the same border width.
