# TIP 496: Display hints in ::entry ::spinbox ::ttk::entry ::ttk::spinbox and ::ttk::combobox Author: René Zaumseil <[email protected]> State: Draft Type: Project Vote: Pending Created: 17-Jan-2018 Post-History: Keywords: Tk Tcl-Version: 8.7 ................................................................................ The **entry**, **spinbox**, **ttk::entry**, **ttk::spinbox** and **ttk::combobox** commands can easily be enhanced to provide this support, and there is no interference with existing code as this functionality can be done by just introducing new options. # Specification A help text can be displayed on **entry**, **spinbox**, **ttk::entry**, **ttk::spinbox** and **ttk::combobox** widgets if no text is otherwise displayed. To control the text appearance the following new options will be added: -placeholder: The string to display. -placeholderforeground: The color of the text. This is a normal option for the Tk widgets and a style option for the Ttk widgets. If the -placeholder text is empty (the default value) then nothing is displayed. The -placeholderforeground has a default value of #b3b3b3 (gray70). The -placeholder text value is always displayed with current font and justification. # Implementation A patch implementing these changes is available in the fossil repository in the tip-496 branch. Documentation updates not yet done. # Example of use package require Tk # tk entry |

# TIP 496: Display hints in ::entry ::spinbox ::ttk::entry ::ttk::spinbox and ::ttk::combobox Author: René Zaumseil <[email protected]> Author: François Vogel <[email protected]> State: Draft Type: Project Vote: Pending Created: 17-Jan-2018 Post-History: Keywords: Tk Tcl-Version: 8.7 ................................................................................ The **entry**, **spinbox**, **ttk::entry**, **ttk::spinbox** and **ttk::combobox** commands can easily be enhanced to provide this support, and there is no interference with existing code as this functionality can be done by just introducing new options. # Specification A help text can be displayed on **entry**, **spinbox**, **ttk::entry**, **ttk::spinbox** and **ttk::combobox** widgets if no text is otherwise displayed. To control the text appearance the following new options will be added: **-placeholder**: The string to display. If empty (the default value) then nothing is displayed. This text value is always displayed with current font and justification. Note that justification can really be honored only if the available display space is large enough to contain the complete text value (this is anyway true also for the widget text itself, see [Tcl Core discussion] (http://code.activestate.com/lists/tcl-core/19657/)). **-placeholderforeground**: The color of the text. This is a normal option for the Tk widgets and a style option for the Ttk widgets. Default value is #b3b3b3 (gray70). # Implementation A patch implementing these changes is available in the fossil repository in the [tip-496 branch] (https://core.tcl.tk/tk/timeline?r=tip-496). Documentation updates not yet done. # Example of use package require Tk # tk entry |
