The class composite diagrams can be placed in a class.
A class composite diagram is created through the Add composite diagram entry of the class browser menu.
The node menu appearing with a right mouse click on its representation in the browser is something like these, supposing the diagram not read-only nor deleted :
show allows to show the diagram picture, and edit it in case it is not read only.
edit allows to show/modify the diagram properties. In case the diagram is read-only, the fields of the dialog are also read-only.
The proposed stereotypes are the default one specified through the Default stereotypes dialog more the current one (empty here). It is possible to choose into the list or to give a new one, or to empty it. The stereotype of a diagram doesn't have a special meaning for BOUML.
The editor button visible above and associated here to the description, allows to edit the description in an other window, or to call an external editor (for instance Xcoral) specified through the environment dialog. Note that this external editor have to create an own window, its parameter is the pathname of the file containing the description, its execution is done in parallel with BOUML which looks each second at the file contents to get the new definition until the dialog is closed (I do not like very much this polling but this works even QT isn't compiled with the thread support).
This dialog allows to specify how the items of the diagram must be drawn by default, you may choose default for each value, in this case the effective value if specified in the upper level (which itself may specify default etc ... up to the project level).
automatic labels position : To ask BOUML to move or to not move the labels associated to the elements when these last are moved.
draw all relations : to automatically draw or not the new connectors, obviously a connector will be added in a diagram only when the start and end elements are drawn.
color gradient : by default the elements are colored without gradient, you can ask for to use a diagonal, vertical or horizontal gradient.
Clone the diagram in a new one
The delete entry is only present when the diagram is not read-only.
Delete the diagram. After that it is possible to undelete it (from the browser) until you close the project : obviously the deleted items are not saved !
See mark
The menu entry tool is only present in case at least a plug-out may be applied on the diagram. The selected tool is called and applied on the current diagram.
The diagram menu appearing with a right mouse click out off any item in the diagram picture is something like these, supposing the diagram not read-only :
Select all the items of the current diagram, may also be done through control a
To find in the diagram a representation of the elements selected in the browser
Similar to the fit scale button, change scale to see all the diagram's elements at great as possible
Similar to the button
,
change the size of the windows to see all the diagram's elements with
the current scale
Copy all the diagram elements, equivalent to a optimal windows size followed by a copy visible picture part then a restore of the original windows size
Put the visible part of the current diagram in the clipboard (copy), it is a screen copy, the current scale have impact on the picture quality.
It is also possible to print all (not only the visible part) the current diagram on printer or a file through the button
To save all the diagram elements in a file, equivalent to a optimal windows size followed by a save visible picture part then a restore of the original windows size
To save the visible part of the current diagram in a file, it is a screen copy, the current scale have impact on the picture quality.
To memorize the current diagram sub window size and the current scale. These ones will be used the next time the diagram will be opened.
To memorize the current scale. These one will be used the next time the diagram will be opened.
In case a preferred sub window size and preferred scale was set, follow them.

By default the diagram's canvas size is 840 x 1188 points corresponding to an iso A4 format (210*4 x 297*4), all the predefined available formats are :
iso A5 : 592 x 840
iso A4 : 840 x 1188
iso A3 : 1188 x 1680
iso A2 : 1680 x 2376
iso A1 : 2376 x 3364
iso A0 : 3364 x 4756
USA A : 864 x 1116
USA B : 1116 x 1728
USA C : 1728 x 2236
USA D : 2236 x 3456
USA E : 3456 x 4472
USA Letter : 864 x 1116
USA Legal : 864 x 1424
USA Tabloid : 1116 x 1728
Each format also exists in landscape (it is Ledger in case of Tabloid)
The menu entry Custom allows to specify the size, the width and height can be set between 400 and 40000.
Undo all the changes made since the diagram was opened the last time. Note that the diagram is restored independently of the the project saving. Obviously the deleted browser items was not restored !
The dialog allowing to set the default stereotypes has a tab reserved for the diagrams :
A class composite diagram may contain role/part, fragment (a priori to indicate the class the composite diagram describes), notes, texts, and the connectors.
To place these elements in the diagram, use the buttons on the top (to create a new element or choose from the already defined ones) then click at the appropriate position in the diagram, or grab the element from the browser into the diagram :
If you drop an attribute of the class owning the diagram and that attribute is typed by a class, a new part is added to the class, named by the name of the attribute and typed by the type of the attribute, and of course that part is added into the composite diagram.
If you drop a composition of the class owning the diagram, a new part is added to the class, named by the role of the composition and typed by the type of the role, and of course that part is added into the composite diagram.
If you drop a relation of the class owning the diagram not being a composition, a new role is added to the class, named by the role of the composition and typed by the type of the role, and of course that role is added into the composite diagram.
Of course you can also drop role, part and connector of the class owning the diagram
To add a new connector between roles/parts/ports, select the connector button on the top of the diagram sub window, click on the start element with the left mouse button, move the mouse, each time the mouse button is raised a new line break is introduced, at least click on the end element. To abort a relation construction press the right mouse button or do a double click with the left mouse button. In case of a port the start/end must be done on the middle square.
A line may be broken, during its construction of after clicking on the line with the left mouse button and moving the mouse with the mouse button still pushed. To remove a line break, a double click on the point with the left mouse button is enough, or use the line break menu of the point using the right mouse button.
By default the lines go to the center of their extremities, to decenter a line click near the desired extremity and move the mouse click down. To come back to a center line, use the menu geometry
The scale may be changed from 30 up to 200 %. To allows to see the operation/message kinds even with a small scale, the size of the arrows is unmodified.
fit% allows to set the largest scale allowing to show all the picture, as it is possible. Because of the scrollbar management, hitting several times on fit% may give several scales.
Classically, the left mouse click may be used to select an element, or several when the control key is down, a multiple selection may also be done defining a region using the mouse left click out of any element and moving the mouse with the click and maintaining the click down. The diagram's elements may be moved after a left mouse click on an element and maintaining the click down during the mouse move. The right mouse click is used to show context dependent menus.
control s is a shortcut to save the project
control shift s is a shortcut to save the project in a new one
control p is a shortcut to print the active diagram
control a is a shortcut to select all the diagram's elements
control d is a shortcut to delete the selected element(s), the model is affected
suppr is a shortcut to remove the selected element(s) from the diagram, these elements are not deleted
control c is a shortcut to copy the selected diagram's elements
control x is a shortcut to cut (remove from diagram) the selected diagram's elements
control v is a shortcut to paste the selected diagram's elements
control z and control u are a shortcut of undo
control r and control y are a shortcut of redo
the keyboard arrows allow to move the selected items
You can define your own shortcut using the shortcut editor through the Miscellaneous menu.
The global menu miscellaneous allows you to show / hide a grid in the background of the diagram.
When several diagram's elements are selected, the menu appearing on a left mouse click allows to align or resize or distribute them :
If all the selected elements has the same kind (for instance all are a part/role), you can edit their drawing settings globally :
You can also reuse the drawing settings set for the first selected element for the other selected elements through the entry Same drawing settings.
A fragment is resizeable. To change the fragment's name choose the edit entry of its menu or double click on it
A right mouse click on a note show the following menu :
Edit drawing settings allows to change the fill color
A note may contain any text, a note is resizeable. To change the text of a note choose the edit entry of its menu or double click on it, this open a window containing the text, close the window to end the edition :
A right click on the edited note calls a dialog allowing some text manipulations thanks Qt.
A right mouse click on a note show the following menu :
The font may be changed, by default the font is the one used to write the other texts.
The color of the text may be changed, a text is black by default.
Edit drawing settings allows to change the fill color
Select linked items select all the items connected this the current one through any line.
Text is another way to write a text, contrary to the note a text is written alone (see “upper diagram :” on the picture below), by default a text contains blabla: a text cannot be empty. The edition of a text is done like for a note. A text is resizeable, a resize is not automatically done when the contains is modified.
A right mouse click on a text show the following menu :
You can directly insert an image independently of the use of stereotype part of a profile, the size of the image is followed when the zoom is 100%. You can resize them, to go back to the initial size of an image just edit it (for instance through a double mouse clic on it) and confirm. Like for a profile the image can be specified through an absolute path, or a path relative to the root directory for the icons or relative to the project directory. In case the path of an icon is not absolute, the icon are searched first using the root directory for the icons, then using the current directory, then using the project directory.
When you insert an image or edit one the following dialog appears :
A right mouse click on an image show the following menu :
