Expecco contains a number of features which might be different or unkown to other UI frameworks, but which are nevertheless very useful to know.
Menus and Toolbars with Delayed Menus
Some menu funtions show a list of choices, if you click it and wait for a while.
Often a list of previous items or other history is presented by this so called "delayed menu".
- If you press and hold, a menu to appear shortly.
- If you just click, without waiting for a menu to appear, the default action will be executed.
- If you click on the arrow, the menu will appear immediately.
These are displayed with a blackish or darker arrow beside them. The menu will drop down immediately.
Toolbar Items which Remember the Last Choice
The item-creation toolbar items above the left tree will remember your last choice, and keep that as default action. These items are of the above described "delayed-menu" type, and will change their image to reflect the previous action's choice.
Resize Handles (between Sub Panes)
Depending on your view style setting, these handles may only show up while the mouse pointer is hovering over it. Some of them are shown with a single arrow (above and below the gritty rubber area, and others are shown with arrows pointing in opposite directions.
If you press-and-hold the mouse button in the center area, these handles behave as known in other UI frameworks: just drag and resize the views underneath.
If you click on one of the arrows, the views' siyes will change to full size towards the arrow. As mentioned above, some only present the fullsize-option on one side.
If one of the views is resized to full size, a single click on the center (not a press-and-move) will restore the previous size, whereas a press-and-move on the handle acts normal.
F8 in the Text Editor
This is a shortcut for the "Again" keyboard function, which repeats your last edit operation. Be it a delete, replace, or search-and-replace. A very powerful operation.
Dual Use of the Tree
The tree has different behavior on Click vs. Press-and-Move. A click selects the element for editing; a press-and-move initiates a drag, to copy the selected element somewhere else.
This behavior may be hindering, if you want to drag and drop actions from the tree. For this, open a separate tree, which is used exclusively for drag&drop (click on the split-tree button above the tree).
It should be noted, that once you are more experiences, you will probably no longer drag&drop from the tree, but instead press CTRL-n in the editor, to place actions via a dialog.
