Solved: Hide Grid In Layout Space
Posted By admin On 10.02.20Snap provides several tools to assist you in laying out questions and adjusting positioning of the separate elements. This worksheet describes adjusting the layout of a grid question.
You will learn:. How to set the grid boxes so that they are vertically centred. How to hide the question number and remove the space left for it. How to change the spacing between the grid elements. How to adjust the page margins Background When you are creating a survey for the Web, you do not have the same control over the way it looks as you do for a paper survey.
Different monitors and different browsers can make surveys look quite different, so it is worth checking it before you put it up on the Web or on Snap WebHost. You also have to consider how the survey will appear in different window sizes, rather than assuming that all the respondents will look at a full-screen window.
Grid layouts that look very sensible in the Snap questionnaire design window may look less attractive when published to the Web. This worksheet describes how to adjust the spacing of a grid question which asks how much the respondent likes different sandwich fillings. It assumes that you have already created the grid question for a Web:HTML or Snap WebHost survey using the default Web template and the default styles. The question looks like this. Step 1: Removing question numbers and centering response boxes vertically The preview shows that the response circles are vertically aligned with the bottom of the row. You can change that by adjusting the alignment. Centre the response boxes vertically.
Click to switch to Style mode. Select All ‘Grid’ Styles in the drop-down list.
Select Alignment from the toolbar topic menu. Select Code Box from the element list. The first box (saying Center in the image) gives the horizontal alignment. The second box (saying Middle in the image) gives the vertical alignment. Step 2: Adjusting the grid question spacing The spacing of a grid question is calculated proportionately to the browser window size.
This is because you do not know how respondents will be viewing your questionnaire. You can define the amount of available space that is given to each element using the Tabs option. The diagram below shows the element names and the areas they affect. Remove the space left for the hidden question numbers. Still in Styles mode, select All Styles from the drop-down list. (If you have switched to design mode in the mean time, remember to click again.).
Select Tabs from the toolbar topic menu. Select Name from the element list.
Detailed Description The class lays out widgets in a grid. Takes the space made available to it (by its parent layout or by the ), divides it up into rows and columns, and puts each widget it manages into the correct cell. Columns and rows behave identically; we will discuss columns, but there are equivalent functions for rows. Each column has a minimum width and a stretch factor. The minimum width is the greatest of that set using and the minimum width of each widget in that column.
The stretch factor is set using and determines how much of the available space the column will get over and above its necessary minimum. Normally, each managed widget or layout is put into a cell of its own using. It is also possible for a widget to occupy multiple cells using the row and column spanning overloads of and.
If you do this, will guess how to distribute the size over the columns/rows (based on the stretch factors). To remove a widget from a layout, call. Calling on a widget also effectively removes the widget from the layout until is called. This illustration shows a fragment of a dialog with a five-column, three-row grid (the grid is shown overlaid in magenta): Columns 0, 2 and 4 in this dialog fragment are made up of a, a, and a. Columns 1 and 3 are placeholders made with. Row 0 consists of three objects, row 1 of three objects and row 2 of three objects.
We used placeholder columns (1 and 3) to get the right amount of space between the columns. Note that the columns and rows are not equally wide or tall. If you want two columns to have the same width, you must set their minimum widths and stretch factors to be the same yourself. You do this using and. If the is not the top-level layout (i.e.
Does not manage all of the widget's area and children), you must add it to its parent layout when you create it, but before you do anything with it. The normal way to add a layout is by calling on the parent layout.
Once you have added your layout you can start putting widgets and other layouts into the cells of your grid layout using , , and. Also includes two margin widths: the and the. The contents margin is the width of the reserved space along each of the 's four sides. The is the width of the automatically allocated spacing between neighboring boxes.
The default contents margin values are provided by the. The default value Qt styles specify is 9 for child widgets and 11 for windows. The spacing defaults to the same as the margin width for a top-level layout, or to the same as the parent layout. Member Function Documentation QGridLayout:: QGridLayout(. parent) Constructs a new with parent widget, parent. The layout has one row and one column initially, and will expand when new items are inserted.
QGridLayout:: QGridLayout Constructs a new grid layout. You must insert this grid into another layout. You can insert widgets and layouts into this layout at any time, but laying out will not be performed before this is inserted into another layout. QGridLayout:: QGridLayout Destroys the grid layout.
Geometry management is terminated if this is a top-level grid. The layout's widgets aren't destroyed. Void QGridLayout:: addItem(. item, int row, int column, int rowSpan = 1, int columnSpan = 1, Qt::Alignment alignment = 0) Adds item at position row, column, spanning rowSpan rows and columnSpan columns, and aligns it according to alignment. If rowSpan and/or columnSpan is -1, then the item will extend to the bottom and/or right edge, respectively.
The layout takes ownership of the item. Warning: Do not use this function to add child layouts or child widget items. Use or instead. virtual protected void QGridLayout:: addItem(. item) Reimplemented from.
Void QGridLayout:: addLayout(. layout, int row, int column, Qt::Alignment alignment = 0) Places the layout at position ( row, column) in the grid. The top-left position is (0, 0). The alignment is specified by alignment. The default alignment is 0, which means that the widget fills the entire cell. A non-zero alignment indicates that the layout should not grow to fill the available space but should be sized according to.
Layout becomes a child of the grid layout. Void QGridLayout:: addLayout(. layout, int row, int column, int rowSpan, int columnSpan, Qt::Alignment alignment = 0) This is an overloaded function. This version adds the layout layout to the cell grid, spanning multiple rows/columns. The cell will start at row, column spanning rowSpan rows and columnSpan columns. If rowSpan and/or columnSpan is -1, then the layout will extend to the bottom and/or right edge, respectively. Void QGridLayout:: addWidget(.
widget, int row, int column, Qt::Alignment alignment = 0) Adds the given widget to the cell grid at row, column. The top-left position is (0, 0) by default. The alignment is specified by alignment. The default alignment is 0, which means that the widget fills the entire cell.
Void QGridLayout:: addWidget(. widget, int fromRow, int fromColumn, int rowSpan, int columnSpan, Qt::Alignment alignment = 0) This is an overloaded function. This version adds the given widget to the cell grid, spanning multiple rows/columns. The cell will start at fromRow, fromColumn spanning rowSpan rows and columnSpan columns. The widget will have the given alignment.
If rowSpan and/or columnSpan is -1, then the widget will extend to the bottom and/or right edge, respectively. QGridLayout:: cellRect( int row, int column) const Returns the geometry of the cell with row row and column column in the grid. Returns an invalid rectangle if row or column is outside the grid. Warning: in the current version of Qt this function does not return valid results until has been called, i.e. After the is visible.
Int QGridLayout:: columnCount const Returns the number of columns in this grid. Int QGridLayout:: columnMinimumWidth( int column) const Returns the column spacing for column column. Int QGridLayout:: columnStretch( int column) const Returns the stretch factor for column column. virtual int QGridLayout:: count const Reimplemented from. virtual Qt::Orientations QGridLayout:: expandingDirections const Reimplemented from. Void QGridLayout:: getItemPosition( int index, int. row, int.
column, int. rowSpan, int.
columnSpan) Returns the position information of the item with the given index. The variables passed as row and column are updated with the position of the item in the layout, and the rowSpan and columnSpan variables are updated with the vertical and horizontal spans of the item.

Void QGridLayout:: setColumnStretch( int column, int stretch) Sets the stretch factor of column column to stretch.
The first column is number 0. The stretch factor is relative to the other columns in this grid. Columns with a higher stretch factor take more of the available space. The default stretch factor is 0. If the stretch factor is 0 and no other column in this table can grow at all, the column may still grow. An alternative approach is to add spacing using with a. See also and.
