Overrides
getAltText()
public String getAltText()
The alternative text that's used for accessibility.
Set descriptive text that lets users know what the button does. For
example, if a button opens a hyperlink, you might write: "Opens a new
browser tab and navigates to the Google Chat developer documentation at
https://developers.google.com/chat".
string alt_text = 6;
| Returns |
|---|
| Type | Description |
String | The altText.
|
getAltTextBytes()
public ByteString getAltTextBytes()
The alternative text that's used for accessibility.
Set descriptive text that lets users know what the button does. For
example, if a button opens a hyperlink, you might write: "Opens a new
browser tab and navigates to the Google Chat developer documentation at
https://developers.google.com/chat".
string alt_text = 6;
| Returns |
|---|
| Type | Description |
ByteString | The bytes for altText.
|
If set, the button is filled with a solid background color and the font
color changes to maintain contrast with the background color. For example,
setting a blue background likely results in white text.
If unset, the image background is white and the font color is blue.
For red, green, and blue, the value of each field is a float number that
you can express in either of two ways: as a number between 0 and 255
divided by 255 (153/255), or as a value between 0 and 1 (0.6). 0 represents
the absence of a color and 1 or 255/255 represent the full presence of that
color on the RGB scale.
Optionally set alpha, which sets a level of transparency using this
equation:
`
pixel color = alpha * (this color) + (1.0 - alpha) * (background color)
For alpha, a value of 1 corresponds with a solid color, and a value of
0 corresponds with a completely transparent color.
For example, the following color represents a half transparent red:
"color": {
"red": 1,
"green": 0,
"blue": 0,
"alpha": 0.5
}
.google.type.Color color = 3;
| Returns |
|---|
| Type | Description |
Color | The color.
