|
* has a stock id, the corresponding stock icon will be
|
|
* used. Otherwise, if the tool button has an icon name,
|
|
* the corresponding icon from the theme will be used.
|
|
* Otherwise, the tool button will not have an icon.
|
|
*
|
|
* - if the tool button has a label_widget then that widget
|
|
* will be used as the label. Otherwise, if the tool button
|
|
* has a label text, that text will be used as label. Otherwise,
|
|
* if the toolbutton has a stock id, the corresponding text
|
|
* will be used as label. Otherwise, if the tool button has
|
|
* an icon name, the corresponding icon name from the theme will
|
|
* be used. Otherwise, the toolbutton will have an empty label.
|
|
*
|
|
* - The use_underline property only has an effect when the label
|
|
* on the toolbutton comes from the label property (ie. not from
|
|
* label_widget or from stock_id).
|
|
*
|
|
* In that case, if use_underline is set,
|

*
|
|
* - underscores are removed from the label text before
|
|
* the label is shown on the toolbutton unless the
|
|
* underscore is followed by another underscore
|
|
*
|
|
* - an underscore indicates that the next character when
|
|
* used in the overflow menu should be used as a
|
|
* mnemonic.
|
|
*
|
|
* In short: use_underline = TRUE means that the label text has
|
|
* the form "_Open" and the toolbar should take appropriate
|
|
* action.
