XmTabList — Data type for a tab list "XmTabList"
#include <Xm/Xm.h> XmTabList
XmTabList is the data type for a tab list. A tab list consists of tab stop list entries (XmTabs). Whenever a tab component is encountered while an XmString is being rendered, the origin of the next X draw depends on the next XmTab. If a tab stop would cause text to overlap, the x position for the segment is reset to follow immediately after the end of the previous segment.
Tab lists are specified in resource files with the following syntax:
resource_spec: tab WHITESPACE [, WHITESPACE tab ]*
The resource value string consists of one or more tabs separated by commas. Each tab identifies the value of the tab, the unit type, and whether the offset is relative or absolute. For example:
tab := float [ WHITESPACE units ] float := [ sign ] [[ DIGIT]*. ]DIGIT+ sign := +
where the presence or absence of sign indicates, respectively, a relative offset or an absolute offset. Note that negative tab values are not allowed. units indicates the unitType to use as described in the XmConvertUnits reference page.
For example, the following specifies a tab list consisting of a one inch absolute tab followed by a one inch relative tab:
*tabList: 1in, +1in
For resources of type, dimension, or position, you can specify units as described in the XmNunitType resource of the XmGadget, XmManager, or XmPrimitive reference page.
