8. Text managing
INDEX
8.1
Some options for the <text> widgetSee reference guide for basic options.
Here follows undocumented options.
Justify aligment to right (1), center (2), left (3).
<text justify="2">
Angle the text
<text angle="45">
Force one-line text
<text wrap="false">
<text single-line-mode="true">
Set underline pattern
<text label="Underline me with an useless pattern" pattern="__ __ __ __ __ __ _"></text>
8.2
Advanced text layoutunderline, italic and Bold.
<text use-markup="true"><label>"<u><i><b>test</b></i></u>"</label></text>
Gtkdialog supports colors and size with the <span> tag. The use-markup="true" must be included.
<text use-markup="true"><label>"<span color='"'#789978'"'>test</span>"</label></text>
Text size is set by the <big> and <small> tags. Repeat (up to 3 times) to increase value.
<text use-markup="true"><label>"<big><big><big>test</big></big></big>"</label></text>
<text use-markup="true"><label>"<small><small><small>test</small></small></small>"</label></text>
Vovchik has made an editor to test advanced text layout,Check it out at http://www.murga-linux.com/puppy/viewtopic.php?t=40418.
8.3
Scroll textThis example shows scrolling text in a <text> widget. This will work for other widgets as well.
export MSG="This is a test... I repeat: This is a test... "
export GTKBOX='
<vbox width-request="300">
<text>
<variable>MSG</variable>
<input>echo -en "${MSG:2}${MSG:0:2}"</input>
</text>
<timer milliseconds="true" interval="200" visible="false">
<action type="refresh">MSG</action>
</timer>
</vbox>'
gtkdialog -p GTKBOX8.4
Strikethrough textStrikethrough text is supported by the use-markup="true" option for text widgets.
<text use-markup="true"><label>"<s>test</s>"</label></text>
This example shows strikethrough on request> /tmp/strikethrough export DIALOG=' <window title="StrikeThrough" icon-name="gtk-strikethrough"> <vbox> <edit wrap-mode="3"> <variable>EDIT</variable> <default>write some text here</default> <height>50</height> </edit> <edit file-monitor="true" auto-refresh="true" wrap-mode="3" editable="false"> <height>50</height> <input file>/tmp/strikethrough</input> </edit> <hbox homogeneous="true"> <button> <label>Strikethrough text</label> <input file stock="gtk-ok"></input> <action>`echo "$EDIT" | sed "s/./&\xCC\xB6/g" > /tmp/strikethrough`</action> </button> </hbox> </vbox> </window>' gtkdialog -p DIALOG
8.5
Set fontThis is an example how to use other fonts even if gtkdialog hasn't an option to set this.
Gtkdialog does not support monospace in the <edit> widget, but I can make it work by adding a unique gtk-theme only for my app. The best way to this is to add my new gtk-theme on top of the already existing. Now my gtk-theme can hold ONLY information about monospace, else it will use gtk-settings specified by user.
By giving the text-widget a name (see example), it is possible to have a gtk-theme for only this unique text string. This also works for text in widgets like <entry>.
echo 'style "specialmono"
{
font_name="Mono 12"
}
widget "*mono" style "specialmono"
class "GtkText*" style "specialmono"' > /tmp/gtkrc_mono
export GTK2_RC_FILES=/tmp/gtkrc_mono:/root/.gtkrc-2.0
export test_app="
<vbox>
<text name=\"mono\"><label>This text-widget uses monospace font....</label></text>
<text><label>...while this text-widget don't.</label></text>
<edit><default>All edit-widgets gets monospace.</default></edit>
</vbox>"
gtkdialog --program=test_app8.6
HyperlinkHyperlink is clickable text, often pointing user to a web page.
<text selectable="true" use-markup="true"> <input>linkstyle "click here"</input> <action signal="button-press-event">defaultbrowser '$LNK'</action> </text>
Other solutions including <eventbox> is discussed at http://murga-linux.com/puppy/viewtopic.php?t=106458
