6.1 Working with the mouse in the ECB-windows

Normally you get best usage if you use ECB with a mouse. ECB distinguishes between a primary and a secondary mouse-button.

With the option ecb-primary-secondary-mouse-buttons the following combinations of primary and secondary mouse-buttons are possible:

If you change this during ECB is activated you must deactivate and activate ECB again to take effect.

6.1.1 The primary mouse-button

A click with the primary button causes the main effect in each ECB-buffer:

6.1.2 The POWER- or SHIFT-click

A click with the primary mouse-button while the SHIFT-key is pressed is called the POWER-click and does the following (depending on the ECB-buffer where the POWER-click occurs):

Per default the complete node-name of an item in a tree-buffer is displayed in the echo-area if the mouse moves over it, regardless if the related window is the active one or not. You get the same effect always after a POWER-click. In general: For each tree-buffer there is an option ecb-*-show-node-info (replace “*” with directories, sources, methods, history or analyse, e.g. ecb-directories-show-node-info is the option for the ECB-directories-window.): you can specify in a detailed manner for the named ECB tree-buffer when and which node-info should be displayed in the minibuffer.

6.1.3 The secondary mouse-button

The secondary mouse-button is for opening (jumping to) the file in another edit-window (see the documentation of the option ecb-mouse-click-destination).

6.1.4 The right mouse-button

In each ECB-buffer mouse-3 (= right button) opens a special context popup-menu for the clicked item where you can choose several senseful actions.

With the options ecb-directories-menu-user-extension, ecb-sources-menu-user-extension, ecb-methods-menu-user-extension and ecb-history-menu-user-extension you can add statically new commands to the popup-menus. See the docstring of ecb-directories-menu-user-extension for more details.

With the options ecb-directories-menu-user-extension-function, ecb-sources-menu-user-extension-function, ecb-methods-menu-user-extension-function and ecb-history-menu-user-extension-function you can add new commands to the popup-menus in a dynamic manner. See the docstring of ecb-directories-menu-user-extension-function for more details.

With the options ecb-directories-menu-sorter, ecb-sources-menu-sorter, ecb-methods-menu-sorter and ecb-history-menu-sorter you can even re-arrange all the entries of the popup-menus.

6.1.5 Horizontal scrolling with the mouse

In each tree-buffer of ECB you can easily scroll left and right with the mouse if the option ecb-tree-easy-hor-scroll is not nil.

The reason for this is: XEmacs has horizontal scroll-bars so invisible parts beyond the right window-border of a tree-buffer can always made visible very easy.

GNU Emacs does not have hor. scroll-bars so especially with the mouse it is quite impossible to scroll smoothly right and left. The functions scroll-left and scroll-right can be annoying and are also not bound to mouse-buttons.

ECB offers three ways for smoothly hor. scrolling with GNU Emacs if ecb-tree-easy-hor-scroll is a positive integer-value S:

This is NOT done for XEmacs cause of its horizontal scrollbars. If you want scrolling left and right with the mouse in XEmacs then activate the horizontal scrollbars.
