Summary:
- EventFilter unnecessary in light of new implemented signal aboutToshow. The data of the drop-down action is updated only when necessary (when it is going to be shown).
- Structure of individual commands under drop-down simplified to a single action, rendering the need for groupcommands obsolete, while keeping all the grid related controls and
the logic for controlling the grid in a single action class.
- Reduce the complexity and overload of isActive to the bare minimum (determining if it is active and updating the icon to the right icon if so).
Refactor:
- Better name for utils functions, as when a DSH is active, the edit mode VPSketch is a data member of DSH, sketchgui (so this function is not really necessary when the DSH is active).
==============================================
ActionGroup may integrate a drop down menu (internally a QMenu).
QMenu has signals aboutToShow and aboutToHide, which are called just before showing/hiding the menu.
This commit extends ActionGroup by providing corresponding signals.
An ActionGroup can be added to more than one toolbar and thus creates more than one menu. So, it can theoretically
happen that you have opened a menu and click on another menu. For this reason, the menu is passed as argument:
void aboutToHideMenu(QMenu*);
void aboutToShowMenu(QMenu*);
- it was frequently requested and people now even published videos since I documented this hidden feature in the Wiki.
However, for a user it is a nightmare without a UI and users who like a bright background need to change the button color to keep the buttons visible.
Support for creation of Rotation from matrices which is a combination of non uniform scale and a rotation
Fixes according to review
Scale -1 is Uniform, Not NoScaling
Fix hasScale() when negative scale
- define materials so that they are recognized by material handling as existing card
- use "electrodynamics" as equation because this is the common name for the physics of these examples
- fix typos
