loadSkin
void loadSkin | ( | DisplayOrientation | orientation , | ||
int | x , | ||||
int | y | ||||
) |
Loads a skin for a given display orientation that will be rendered in the simulator window with the the TouchGFX framebuffer placed inside the bitmap at the given coordinates.
Different bitmaps can be loaded in landscape and portrait mode. If the provided bitmap cannot be loaded, the TouchGFX framebuffer will be displayed as normal. If the png files contain areas with alpha < 255, this will be used to create a shaped window.
orientation | The orientation. |
x | The x coordinate. |
y | The y coordinate. |
Note
The skins must be named "portrait.png" and "landscape.png" and placed inside the "simulator/" folder. The build process of the simulator will automatically copy the skins to the folder where the executable simulator is generated. When as skin is set, the entire framebuffer is rendered through SDL whenever there is a change. Without a skin, only the areas with changes is rendered through SDL.

char * localFileName | ( | char * | buffer , | ||
size_t | buffer_size , | ||||
const char * | filename | ||||

bool | redrawWindow =true | ||||

shown).

redrawWindow | (Optional) Should the window be redrawn? Default is true. |
setFlashInvalidatedAreas
virtual void setFlashInvalidatedAreas | ( | bool | flash =true | ) | |
Flash invalidated areas on/off.
The area that needs to be redrawn is flashed in grey to help identify performance bottle necks.
flash | (Optional) True to flash the screen when updating. |
setFrameBufferSize
virtual void setFrameBufferSize | ( | uint16_t | width , | ||
uint16_t | height | ||||
) |
Sets framebuffer size.
By default the display size and the framebuffer size are the same, but in some hardware configurations, the hardware may have a width of e.g. 832 pixels even though the display is only 800 pixels wide. First set the display width and height using touchgfx_generic_init() and the update the framebuffer size using setFrameBufferSize().
width | The width of the framebuffer. |
height | The height of the framebuffer. |
Reimplements: touchgfx::HAL::setFrameBufferSize
setVsyncInterval
void setVsyncInterval | ( | float | ms | ) | |
Sets vsync interval for simulating same tick speed as the real hardware.
Due to limitations in the granularity of SDL, the generated ticks in the simulator might not occur at the exact time, but accumulated over several ticks, the precision is very good.
ms | The milliseconds between ticks. |
Note
That you can also use HAL::setFrameRateCompensation() in the simulator. The effect of this can easily be demonstrated by dragging the console output window of the simulator (when running from Visual Studio) as this will pause the SDL and generate a lot of ticks when the console window is released. Beware that since the missed vsyncs are accumulated in an 8 bit counter, only up to 255 ticks may be missed, so at VsyncInterval = 16.6667, dragging the windows for more than 255 * 16.6667ms = 4250ms = 4.25s will not generate all the ticks that were actually missed. This situation is, however, not very realistic, as normally just a couple of vsyncs are skipped.
setWindowVisible
void setWindowVisible | ( | bool | visible , | ||
bool | redrawWindow =true | ||||
) |
Change visibility of window (hidden vs.
shown) as well as (due to backward compatibility) the visibility of the console window.

redrawWindow | (Optional) Should the window be redrawn? Default is true. |
