◆ click_dismiss_

bool gui2::window::click_dismiss_

private

Do we want to have easy close behavior?

Easy closing means that whenever a mouse click is done the dialog will be closed. The widgets in the window may override this behavior by registering themselves as blockers. This is tested by the function disable_click_dismiss().

The handling of easy close is done in the window, in order to do so a window either needs a click_dismiss or an ok button. Both will be hidden when not needed and when needed first the ok is tried and then the click_dismiss button. this allows adding a click_dismiss button to the window definition and use the ok from the window instance.

Todo:: After testing the click dismiss feature it should be documented in the wiki.

◆ mouse_button_state_

int gui2::window::mouse_button_state_

private

The state of the mouse button.

When click dismissing a dialog in the past the DOWN event was used. This lead to a bug [1]. The obvious change was to switch to the UP event, this lead to another bug; the dialog was directly dismissed. Since the game map code uses the UP and DOWN event to select a unit there is no simple solution.

Upon entry this value stores the mouse button state at entry. When a button is DOWN and goes UP that button does not trigger a dismissal of the dialog, instead that button's down state is removed from this variable. Therefore the next UP event does dismiss the dialog.
